Seabed mining permit approved in New Zealand blue whale habitat

By Dawn Barlow, MSc Student, Department of Fisheries and Wildlife, Geospatial Ecology of Marine Megafauna Lab

In late February, we wrapped up our 2017 blue whale survey of the South Taranaki Bight region. Upon returning to port in Wellington, Leigh and I each located our one remaining clean shirt, drank a cup of coffee, and walked into a room full of lawyers in suits where Leigh testified in front of the Environmental Protection Authority’s (EPA) Decision Making Committee. The hearing was for Trans-Tasman Resources, Ltd. (TTR)’s application for a permit to extract 50 million tons of iron sands per year from the sea floor for a 35-year period. Our reason for being there? Leigh was called as an expert witness to present our findings on blue whale distribution and ecology in the region where the proposed mining operation will be so that the potential impacts could be properly evaluated by the Decision Making Committee. Talk about seeing an immediate application of your research!

Fast forward several months. The decision of whether or not the permit will be granted has been delayed, more evidence has been requested and considered, Leigh has testified again via skype, and the decision has been delayed yet again. It is a contentious case, and people on both sides have grown impatient, concerned, and frustrated. Finally, the date and time of the decision announcement finds me nervously refreshing my browser window until I see the outcome: the mining permit has been approved.  It was a split decision by the committee of four, with the committee chair casting the deciding vote.

While the Decision Making Committee was split on whether or not the permit should be approved, the constituency was not. During the hearing process, over 13,700 submissions were received, 99% of which were in opposition to the mining operation. Opposition came from Iwi (Maori tribes), commercial and recreational fishing industries, scientists, and residents of local coastal communities.

What does this mean for New Zealand, for the whales, for the ecosystem, for the future? This decision represents a landmark case that will surely set a new precedent. It is the first of its kind to be approved in New Zealand, and the first commercial scale seabed mining operation in the world. Other permit applications for seabed mines elsewhere will no doubt be submitted in the wake of the approval of TTR’s iron sands mining operation. The groups Kiwis Against Seabed Mining and Greenpeace New Zealand have announced that they will appeal the EPA’s decision in High Court, and TTR cannot begin dredging until all appeals are heard and two years of environmental monitoring have taken place.

So for the time being, life continues as usual for the blue whales. They will carry on feeding and raising their young in the South Taranaki Bight, where they already are surrounded by oil rigs, vessel traffic, and seismic airguns. In the meantime, above the water’s surface, many dedicated individuals are prepared to fight hard for environmental conservation. The blue whales will likely continue to unknowingly play a role in the decision-making process as our data demonstrate the importance of this region to their ecology, and the New Zealand public and media continue to learn about these iconic animals. The research effort I am part of has the potential to immediately and concretely influence policy decisions, and I sincerely hope that our findings will not fall on deaf ears in the appeal process. While we continue to provide biological evidence, politicians, the media, and the public need to emphasize the value of preserving biodiversity. These blue whales can be a figurehead for a more sustainable future for the region.

Diving Deeper

By Taylor Mock, GEMM Lab intern

Greetings, all!

My name is Taylor Mock. Since February I have been volunteering in the GEMM Lab and am ecstatic to make my online debut as part of the team!

For many years, I had a shallow relationship with Hatfield Marine Science Center. As a Newport native, I would spend mornings and evenings glancing over at the Hatfield buildings while driving over the bridge to and from school. I was always intrigued. Sure, I would hear snippets of research from my peers about what projects their parents were involved in, but the inner workings of the complex mystified me.

Toward the end of my Freshman year in 2012 at Westmont College in Santa Barbara, California, my mom asked me what my summer plans were. I replied with the typical “I don’t know… Get a job?” She insisted that instead of a job I think about getting an internship; experience that will last more than a summer. I inquired through a family friend (because every person in this little community is woven together some way or another) if any internships or volunteer opportunities were available at Hatfield. She pointed me in the direction of the Environmental Protection Agency and thus began my Hatfield volunteering saga. I worked that summer, and the next, at the EPA under the direction of Ted DeWitt and Jody Stecher on denitrification studies in estuarine marshes. That summer provided me a glorious front row seat to field research and a greater understanding of my potential as a person and as a scientist. Now, this experience was marvelous, but I knew shortly after starting that my heart was elsewhere.

It was during my study abroad semester in Belize as part of my internship at the Toledo Institute for Development and Environment (TIDE) that I realized I wanted to work with marine macroorganisms. At TIDE, I engaged in radio telemetry conservation efforts tracking Hicatee (Dermatemys mawii) aquatic turtles. We would spend days on a small boat floating through canals and setting nets in hopes of capturing individuals of this small population to outfit them with radio tracking devices. These would be later used to track foraging, mating, and travel patterns in the region. It was an amazing time, to say the least. I remember waking up on my 21st birthday from my camping hammock and staring up at the lush rainforest above my head with a warm breeze across my face, followed by spending the day in the presence of these glorious creatures. It was heaven. I returned to Westmont the following term and took a Marine Mammal Eco-Physiology course and absolutely fell in love with Cetacea. Yes, I had always been captivated by this clade of beings (and truthfully when I was eight years old had a book on “How to Become a Marine Mammal Trainer”), but this was deeper. Of course, pinnipeds and otters and polar bears and manatees were enjoyable to learn about. There was something about the Cetacea though and how they migrated up and down the coast (just like me!) that I really connected with. My time learning about these animals created an intimate understanding of another group of species that developed into a rich, indescribable empathetic connection. I had to take a couple years away from scholastics and away from biology for health and wellness reasons. One day, though, a couple years after graduating and returning to Newport I rekindled with Jody from the EPA. He asked me if I would like to volunteer under Leigh Torres in the Marine Mammal Institute at HMSC. I do not think I could have possibly said no. I have been enjoying my time in the GEMM Lab ever since!

Though I am available to help anyone with any task they need, the work I do mostly centers around photogrammetry.

Using photogrammetry skills to measure gray whales in the GEMM Lab.

Photogrammetry, essentially, means geo-spatially measuring objects using photographs. What that looks like for me is taking an aerial photograph (extracted from overhead drone video footage) of a whale, running the image through a computer program called “Matlab”, taking a series of measurements from the whale (e.g., tip of the mandible to the notch of the fluke, distance between each tip of the fluke, and several measurements across the midsection of the whale). Several images of individuals are processed in order to find an average set of measurements for each whale.

Final result of the photogrammetry method on a gray whale

You might be wondering, “How can one measure the distance accurately from just a photograph?” I am glad you asked! The drones are outfitted with a barometer to measure the atmospheric pressure and, in turn, altitude. The changing altitudes are recorded in a separate program that is run simultaneously with the video footage. Thus, we have the altitudinal measurements for every millisecond of the drone’s flight. To monitor the accuracy and functionality of the barometer, calibrations are completed upon deployment and retrieval of each drone flight. To calibrate: the initial takeoff height is measured, a board of known length is thrown into the water, the drone will then rise or lower slowly above the board between 10 and 40 m, photographs of the board are then taken from varying altitudes, and are processed in Matlab.

During my time in the GEMM Lab, I have had the pleasure of completing photogrammetry assignments for both Leila on the Oregon Coast gray whale and for Dawn on the New Zealand blue whale projects. These ladies, and the other members of the GEMM Lab, have been so patient and gracious in educating me on the workings of Matlab and the video processing systems. It is a distinct honor working with them and to delight in the astounding nature of these creatures together. Each day I am struck in sheer awe of how beautiful and powerful these whales truly are. Their graceful presence and movement through the water rivals even the most skillful dancer.

Over the last 6 years, I am delighted to say that my relationship with Hatfield has become much deeper. The people and the experiences I have encountered during my time here, especially in the GEMM Lab, have been nothing short of incredible. I am sincerely grateful for this continued opportunity. It fills my soul with joy to engage in work that contributes to the well being of the ocean and its inhabitants.

Thank you, Leigh and all of the GEMM Lab members. I hope to continue volunteering with you for as long as you will have me.

The passion of a researcher

By Quince Nye, GEMM Lab Summer Intern, Pacific High School Junior

I have spent a lot of my life surrounded by nature. I like to backpack, bike, dive, and kayak in these natural environments. I also have the luck of having parents who are always planning to take me on another adventure where I get to see nature and its inhabitants in ways most people don’t get to enjoy.

Through my backyard explorations, I have begun to realize that Port Orford has an amazing ecosystem in the coves and rivers that are very tied into our community. I’ve fished and swam in these rivers, gone on kayaking tours in these coves (with a great kayak company called South Coast Tours that we partner with), and I’ve seen the life that dwells in them.

Nathan and Maggie paddle out to Mill Rocks for early morning sample collection

Growing up in a school of less than 100 kids I have learned to never reject an opportunity to be a part of something bigger and learn from that experience. So when one of my close friends told me about an OSU project (a college I’m interested in attending) that needed interns to help collect data on gray whales, and kayak almost every day, I signed up without a doubt in my mind.

The team gets some good practice tracking Buttons (Whale #3).  Left to right; Quince, Nathan, Maggie, Florence.

Fast forward a month, and I wake up at 5:20 am. I eat breakfast and get to the Port Orford Field Station. We make a plan for the operations of both the kayak team and cliff team. Today, I’m part of the cliff team, so I head up above the station to Fort Point. Florence and I set up the theodolite and computer at the lookout point and start taking half hour watch shifts searching the horizon for the spout of a gray whale.  Sometimes you see one right away, but other times it feels like the whales are actively hiding from you. These are the times I wish Maggie was here with her endless supply of Disney soundtracks to help pass the hours.

Imitating a ship’s captain, Quince points toward our whale while shouting “Mark”.

A whale spouts out at Mill Rocks and starts heading across to the jetty. Hurray, its data collection time! I try to quickly move the cross-hairs of the theodolite onto the position of the whale using a set of knobs like those on an etch-a-sketch. As you may understand, it’s not an easy task at first but I manage to do it because I’ve been practicing for three weeks. I say “Mark!” cueing Florence to click a button in the program Pythagoras on the computer to record the whale’s position.

The left hand side of Buttons – notice the scatter of white markings on the upper back.

Meanwhile, Florence sees that the whale has two white spots where the fluke meets the knuckles. Those are identifying marks of the beloved whale, Buttons. This whale has been seen here since 2016 and is a fan favorite for our on-going research program. Florence gets just as excited every time and texts her eagerly awaiting interns of previous years all about the sighting. Of course Buttons is not the only whale to have identifying marks such as scars and pigmentation marks. This is why we make sure to get photos of the whales we spot, allowing us to do photo-ID analysis on them through comparison to our database of pictures from previous years.

Quince practices CPR protocol on a training mannequin on his first day.

So far I have gained skill after skill in this internship. I got CPR certified, took a kayak training class, learned how to use a theodolite, and have spent many educational (and frustrating) hours entering data in Excel. I joined the program because I was interested in all of these things. It surprised me that I was developing a relationship with the whales I’m researching. By the end of August I’m now sure that I will also know many of the whales by name. I will probably be much better at using an etch-a-sketch, and I will have had my first taste at what being a scientist is like. What I strive for, however, is to have the same look in my eyes that appears in Florence’s whenever a familiar whale decides to browse our kelp beds.

Curiosity and Community, new ways of exploring our environment.

By Nathan Malamud, GEMM Lab summer intern, Pacific High School senior

I am someone who has lived in a small town for all his life. Pretty much everyone knows each other by their first name and my graduating class only has around 20 people. Everywhere you look you will find a farm, ranch, or cranberry bog (even our school has two bogs of their own!). Because of my small town life, I have a strong sense of community. However, I have also developed a curiosity about natural and global phenomena. I try to connect these two virtues by participating in scientific efforts that help my community. When I heard that the OSU Port Orford Field Station was offering internships, I knew right away that it would definitely be a great experience for me.

The view from our field site at Fort Point in Port Orford

Port Orford, on Oregon’s southern coast, is a town that is closely tied to the ocean. So naturally, it’s important to understand and monitor our surroundings so that our town can thrive. Last year, my Marine Science class helped me further understand the complexity of the ocean. Our first semester taught us all about marine biology, zoology, and ecology. Our second semester immersed us into oceanography, ocean geology, and ocean chemistry. During the second semester, we also took trips to our town’s marine science center and to the marine reserve near Rocky Point. I loved this course and decided to try to expand my knowledge about the subject by going to the OSU Field Station.

Our safety instructor teaches takes us through basic paddling techniques

As an intern, I am currently working with three teammates to understand the feeding behavior of gray whales – what places they like to eat zooplankton the most and why they like to eat there. This whale project helps our community by Port Orford enabling high school students to perform college-level scientific research and inquiry, as well as allowing us to learn valuable skills such as CPR, surveying using a theodolite, working with chemicals in a lab, and data processing.

We had to learn how to rescue ourselves just in case we have an accident in the boat.
We all made it back in the boat!

This internship with OSU’s GEMM Lab has taught me many new skills and given me new experiences that I have never had before. Before this internship, I had never been in a kayak. Now, I go out on the water nearly every other day! When on the water, I always try to sharpen my navigating skills. I use a GPS to pinpoint the locations of our sampling stations, and I communicate to my partner where we need to go and how we will get there.

Its very important to stretch before kayaking every morning.

Once we are there, it is my job to keep the boat close to the station location so that my partner can get accurate samples. This part is a very tricky task, because not only do I have to pay attention to the GPS to make sure we are within 10 meters of the spot, but I also have to pay attention to my surroundings. I have to look at the ocean, and figure out what direction the waves are coming from. I have to watch how external forces, like wind and currents, can cause the boat to drift far from station, and I have to correct drifting with gentle paddle strokes. This is hard, especially since the kayak is so light and easy to get pushed around by the wind. However, despite the difficulty, I have learned that it is crucial not to panic. Frustration only makes things worse. The key is to maintain a harmonic balance of concentration and zen.

I have also learned that when collecting data in the field, it’s important to observe and document as much as possible. When we are in the kayak, we have 12 stations that we try to visit every day (as long as the weather cooperates). At each station, we first use a secchi disk to test the water clarity, then lower the GoPro to film the water column and see where the zooplankton are. Sometimes we catch other interesting things on the video too, such as siphonophores (my personal favorites are jellies and salps) and rockfish.

Next we tow a zooplankton net through the water, and let it collect zooplankton of all shapes and sizes, from tiny mysids to skeleton shrimp. Then we proceed to the next station and repeat the process. We have to remember to label everything, and tell the GoPro camera what station we’re at so we can sort all the information correctly when we get back to the field station. At the end of the day, we log our data into a computer, and preserve half our plankton samples with ethanol, so that we can identify the species present.  The other half gets frozen for caloric content analysis by our collaborator Dr. Kim Bernard to help us understand how much zooplankton a whale needs to eat to meet its energy needs each day.

By repeating this entire process every day, we are able to look at daily changes, which also helps us to better understand why whales spend time in certain areas and not others. Be sure to check out my teammate Maggie’s blog post about some of the tools and technologies we use to track the whales!

This whale project has been, and definitely still is, a great experience for me! I have learned a lot and have worked with some amazing people. I believe that I am learning many valuable skills, and that the skills I learn will allow me to help my community.

A Little Slice of Heaven

Guest writer: Maggie O’Rourke-Liggett, GEMM Lab summer intern, Oregon State University,

One of the biggest obstacles an undergraduate can face is fulfilling the degree requirement of completing an internship or research opportunity. With almost every university and degree program requiring it for graduation and many employers requiring prior experience, the amount of pressure and competition is intense.

After being rejected from the internships I applied for earlier in the year, I heard about Dr. Leigh Torres’s research with the Geospatial Ecology of Marine Megafauna (GEMM) Lab . I decided to email her and ask if she had any open positions. Fast-forward a few weeks and I am collaborating with Florence Sullivan, a recent masters graduate from OSU, on the logistics of my Gray Whale Foraging Behavior internship with the GEMM Lab.

During my time with the GEMM Lab team, I have been assisting with photo identification analysis of gray whales (Eschrichtius robustus), using a theodolite and Pythagoras computer program to track their movements, collecting samples of the zooplankton they eat, and recording other oceanographic data with our time-depth recorder. This project is hoping to identify the drivers of gray whale fine-scale foraging behavior.  For instance: Why do gray whales spend more time in some areas than others?  Does the type or density of prey affect their behavior? Do the whales use static features like kelp beds to help find their food? As a senior currently studying oceanography, who desires to study whale behavior in the future, this internship is like finding a gold mine.

Ever since day one at Hatfield Marine Science Center, I’ve been working with people who share the same passions for marine mammals as me. Spending hours upon hours sorting thousands of pictures may seem like a painful, tedious job, but knowing my work helps others to update existing identification catalogs makes it worthwhile. Plus, who wouldn’t want to look at whales all day?! After a while, you start to recognize specific individuals based on their various pigment configurations and scars. Once you can recognize individuals, it makes the sorting go by faster and helps with recognizing individual whales in the wild faster. It’s always exciting to sort through the photos and observe from the cliff or kayak and recognize a whale from the photo identification work.

After Florence taught me how to set up and operate the theodolite, a survey tool used to track a whale’s movements, we taught a class to undergrads on how to use it. I’ll never get over how people’s faces lit up when we discussed how the instrument works and its role in the overall mission.

These past two weeks at OSU’s Port Orford Field Station have been like living on a little slice of heaven. My days are filled with clear views of the coast and the sound of waves crashing serve as a backdrop on my home for the month, the bed-and-breakfast turned field station. Each morning, the sun fills my room as I gather my gear for the day and help my teammates load the truck. We spend long days on the water collecting zooplankton samples and GoPro video or on the cliff recording whale behavior through the theodolite. To anyone searching for an internship and feeling burnt out from completing application after application, don’t give up. You’ll find your slice of heaven too.
