My work this week has been defined by many miscellaneous tasks I have done for various members of my mentor’s lab, almost none of which are related to my project, but I had a lot of fun with them. I have done analysis of videos taken in an estuary in Washington, measured tiny mud shrimp recruits (juveniles) after sorting through mud to find them, and measured, sexed, and examined adult mud shrimp to look for parasites and infection. I also “tested” the GoPro cameras we will be deploying in July to record the fish and crabs found in the invasive species of eelgrass.

Today was the first day I went out in the field to do sampling, on the mudflats near Hatfield Marine Science Center. Thank goodness it was a beautiful day today, so we didn’t have to wear heavy rain gear. We got very muddy, and I wish I had pictures but I don’t have a camera I wouldn’t mind getting dirty. We were looking for mud shrimp to measure and look for parasites. We used what is called a bucket core, which looks like a giant stainless steel bucket without a bottom and is about three feet tall. We pushed it all the way down into the mud, and shoveled the mud out into sieves, sorting through them and pulling out the shrimp as we found them. It was hard work, but the most fun I’ve had so far, and a great excuse to get outside and play in the mud!

Overall, it was a great week. I also bought a new camera, so hopefully I’ll have some higher quality pictures from now on. Next week I’m looking forward to building the mounts for our cameras and testing them in the field, and the Fourth of July, of course!

Hello!

My name is Sarah Heidmann, and I am one of the Summer Scholars this year for Oregon Sea Grant. I attend Oregon State University, and will be graduating in June 2014. I’m majoring in biology with the marine option, and minoring in statistics. I am originally from California, but am loving my experiences so far in Corvallis and Newport studying marine biology. This past spring term at OSU I lived in Newport taking an intensive marine biology course, and am excited to put all my new knowledge to the test.

Although I am working in Newport, I am living in Corvallis. Since OSU’s main campus is there, it was easier for me to live in the house I will have throughout the next year, in addition to being able to be with my friends who are here this summer. It’s about an hour driving distance, and I’ve been riding in a vanpool that allows me to sleep both ways, but I still have to get up pretty early.

This summer I am working in Newport with the US Department of Agriculture (USDA-ARS) studying fish and invertebrate use of coastal estuarine habitats. We are focusing on the habitat provided by a non-native species of seagrass, Zostera japonica, using GoPro cameras to record video in different areas and analyzing the numbers of fish and crabs that appear in the field of view. I’ll be in the field a lot this summer, getting very muddy.

So far I’ve been mostly practicing analysis of video from past years, trying to find some ways of improving the sampling technique. Although I’ve had some previous research experience, I still have so much to learn! I have been getting some training in Microsoft Access databases as well as statistics using R, which has a very steep learning curve when you have never programmed before. It seems like I’ll gain a some skill sets this summer that will be very useful farther down the road in my career.

Thanks for taking the time to read about my adventures! I am greatly looking forward to the rest of the summer.
