Hatfield is an amazing facility and the fact that it is comprised of many different agencies made the REU experience unique. I definitely enjoyed the exposure to a wide array of research and appreciated how easy it was to explore different labs. Participating in the REU was a very rewarding experience in which I was able to be a part of cutting edge climate change research. 

This past summer, I worked with Bill Peterson and his NOAA lab to investigate the effects of ocean acidification on hatching and development of two copepod species, Calanus pacificus and Calanus marshallae, and one species of euphausiids, Euphausia pacifica. We found evidence that decreasing pH slows development for all three species. There were no significant differences in hatching success between the pH treatments, but a larger proportion of larval deformity was observed for all species in the lower pH treatments. My research included participating in bi-weekly cruises to collect gravid females for my experiments. In August, I participated in a week-long research cruise with the Peterson lab on the NOAA ship the Miller Freeman. While on these cruises I performed technician responsibilities that included water-column sampling for chlorophyll analysis, plankton net tows, and CTD deployment. I look forward to presenting my research at the 2011 American Society for Limnology and Oceanography (ASLO) conference this February in Puerto Rico.
