In a recent publication for the The Journal of the Acoustical Society of America, Stimpert and Madrigal studied noise produced by scientific equipment during fisheries surveys so as to better understand how this noise affected the general soundscape of a rockfish habitat. Anthropogenic noise, in this study, was found to be out of the expected sensitivity range for fish hearing. However, this is a largely unstudied section of fisheries research and in other cases could effect stock assessments. The open access scientific article also includes recording samples you can hear.
California Sea Grant today announced funding for a total of 19 new research projects that will take place over the next one to two years. A total of $900,000 will go to 19 research projects led by California investigators and graduate students. We are PROUD to announce that our professor of ichthyology, Dr. Scott Hamilton, is one of the grant recipients. This year for the first time, CA Sea Grant solicited project proposals directly from graduate students. We are therefore doubly PROUD to announce that Dr. Hamilton's student Katherine Neylan, is also a recipient thanks to the graduate fellowship in aquaculture.
Development of techniques for the cultivation of monkeyface pricklebacks as a sustainable alternative to unagi
For this project, Dr. Hamilton is interested in using a local fish, the monkeyface prickleback, as a farmed and sustainable alternative to unagi (the seafood cuisine of sea urchins). Co principal investigators include our phycology professor, Dr. Mike Graham, as well as, Dr. Luke Gardner both a research faculty member and the CA Sea Grant Aquaculture Specialist.
Eat your greens: Evaluating microalgae supplemented feeds for sablefish nutrition and growth
Ichthyology student, Katherine Neylan will study the nutrition and growth of sablefish given a microalgal diet. Currently, farm-raised fish rely on a diet that is heavily dependent on the use of forage fish in fish meal and fish oil. However, allocating the proper nutrients to a farmed fish via ocean resources can place a significant strain on forage fish stocks. The project therefore seeks to formulate a diet that incorporates algae and meets nutritional needs while also examining the palatability and digestibility of it for sablefish.
In Geophysical Research Letters, Dr. Dustin Carroll, a SJSU/MLML research affiliate, co-authored the article, Distinct Frontal Ablation Processes Drive Heterogeneous Submarine Terminus Morphology. Using ship-based observations in Greenland fjords, Dr. Carroll and his collaborators mapped the subsurface, three dimensional face of a glacier to better understand how they melt from warming ocean waters.

Former director of MLML, Dr. John Martin, was recognized in this article from Nature Research (Publishing) on the 30th anniversary of his revolutionary, Iron Hypothesis. His work was continued by Dr. Kenneth Coale, who also served as director to the labs and is now an emeritus professor of chemical oceanography. From the article:
Thirty years ago this month, John Martin proposed a solution to one of the biggest mysteries of Earth’s climate system: how was nearly one-third of the carbon dioxide in the atmosphere (about 200 gigatonnes of carbon) drawn into the ocean as the planet entered the most recent ice age, then stored for tens of thousands of years, and released again as the ice sheets melted?
For more on Dr. Martin and his legacy, here is a piece about him written by Dr. Coale for the 50th Anniversary Blog.
SJSU/MLML professor of physical oceanography, Dr. Tom Connolly, and co-author, Dr. Anthony R. Kricinch of Woods Hole Oceanographic Institution, recently published in the Journal of Geophysical Research: Oceans. Their article, "High-resolution observations of subsurface fronts and alongshore bottom temperature variability over the inner shelf", found that drastic variations in water temperatures occurred often and within short distances along Martha's Vineyard coastline which were caused by several influences, such as bathymetry. In terms of data collection, this information is valuable to scientists because it demonstrates the need to take temperature readings at multiple locations within the study area.
