Dr. Jim Harvey retires from SJSU/MLML after 32 years

After 32 outstanding years of service to Moss Landing Marine Laboratories and San José State University, today marks Dr. Jim Harvey’s last day as our Director. Please join us in congratulating Jim on his well deserved retirement!

Jim first came to SJSU/MLML as a graduate student in 1974 and has since served as a course instructor, professor, and ultimately lab director for the last decade. He led the Vertebrate Ecology Lab for 20 years, during which time he advised 82 students and served on 132 total thesis committees. Broadly, Jim’s research interests include the ecology, morphology, and behavior of marine mammals, birds, and turtles, with a special focus on the harbor seal population of Elkhorn Slough.

Jim’s contributions to the MLML community over the course of his long career are innumerable and we will miss his steadfast leadership, collegial spirit, and commitment to research and teaching excellence. While Jim is officially retiring from his position as director, he will continue his research and looks forward to spending more time in the field. Current MLML professor and department chair Dr. Ivano Aiello will serve as Interim Director of Moss Landing Marine Labs until a permanent Director has been appointed.

Professor Gitte McDonald featured in National Geographic video about emperor penguins

Many campers have probably encountered a curious squirrel or hungry raccoon trying to break into their tent… but what about a pack of mischievous penguins? SJSU/MLML professor and Antarctic researcher Dr. Gitte McDonald is no stranger to the antics of these large seabirds.

Dr. McDonald and her colleagues were recently featured in a new video from National Geographic about the hilarious penguin invasion of their field camp in Antarctica. Check out the video here.

SJSU/MLML alumna Nancy Black establishes non-profit California Killer Whale Project

The California Killer Whale Project (CKWP) is a new non-profit dedicated to the study of killer whales (Orcinus orca) along the California coast. While the organization was officially established in December 2019, their research has been going on for decades and their database of killer whale sightings spans the past 66 years. The mission of CKWP is to continue the long-term study of the ecology, natural history, and conservation of California's killer whales. CKWP CEO and co-founder Nancy Black received her MS in Marine Science from Moss Landing Marine Laboratories in 1995 and has spent the last three decades studying the killer whales of Monterey Bay.

Professor Gitte McDonald receives prestigious NSF CAREER Award

MLML is excited to announce that Dr. Birgitte (Gitte) McDonald, faculty member of San José State University, has been awarded a CAREER Award from the National Science Foundation for $935,931. The Faculty Early Career Development Program (CAREER) supports promising young scientists, providing funds to allow them to greatly expand their research capability in the early stages of their career. Dr. McDonald will be using the funds to support graduate students and postdocs, develop a new biologging course, and contribute data to an NSF-funded afterschool program. Dr. McDonald’s research program is described below.

As ice-dependent top predators, Emperor Penguins are indicators of both drastic and subtle changes occurring throughout the food web and the state of the sea ice. Like other predators, they are vulnerable to environmental change: these changes permeate through the food web, modifying foraging behavior, and ultimately survival and reproduction. Despite their importance in the Southern Ocean ecosystem, relatively little is known about the mechanisms Emperor Penguins use to find and acquire food. This study combines a suite of technological and analytical tools to gain essential knowledge on Emperor Penguin foraging energetics, ecology, and habitat use during critical periods in their life history.

Specifically, this project (1) investigates the foraging energetics, ecology, and habitat use of Emperor Penguins at Cape Crozier, the 2nd most southern colony, during late chick-rearing. Energy management is particularly crucial during late chick-rearing as parents need to feed both themselves and their rapidly growing offspring, while being constrained to regions near the colony. And (2) study the ecology and habitat preference of Ross Sea Emperor Penguins after the molt and through early reproduction. The post-molt foraging trip may be the most dangerous time for Emperor Penguins as they recover from a 50% loss in protein, while doubling their body mass for the reproduction fast ahead of them. This study fills important knowledge gaps on the energy balance, diet, and habitat use of Emperor Penguins during these critical periods, while also addressing fundamental questions in ecology.

Alumna Brijonnay Madrigal awarded NOAA Dr. Nancy Foster Scholarship

MLML alumna Brijonnay Madrigal was recently named a 2020 Nancy Foster Scholar! The highly competitive NOAA Dr. Nancy Foster Scholarship Program supports women and minorities pursuing graduate research in oceanography and marine biology.

Bri received her MS in Marine Science from MLML in 2019. Her master’s thesis research through our Vertebrate Ecology Lab examined the acoustic behavior of killer whales from the Bering and Chukchi Sea in Alaska. She will be heading to the University of Hawaii at Manoa to begin her PhD in the fall.

Vertebrate Ecology Lab bioacousticians publish new rockfish study

Dr. Alison Stimpert and recent alumna, Brijonnay Madrigal, M.S. from our Vertebrate Ecology Lab, have applied their bioacoustic research skills from marine mammals onto rockfish.

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.

MLML Seminar Room

Brijonnay Madrigal is a master's student working under the co-advisement of Alison Stimpert and Birgitte McDonald in the Vertebrate Ecology Lab. She graduated from the University of Hawai’i at Mānoa in 2016 with a B.S. in Marine Biology and a B.A. in Communication. Prior to her time at Moss Landing, as an undergraduate and Ernest F. Hollings scholar, she completed a research internship at the NOAA Southeast Fisheries Science Center, where she determined sperm whale abundance from passive acoustic monitoring. She later worked as a research assistant for a project conducted in collaboration with both the U.S. Navy and the Hawai’i Institute of Marine Biology Marine Mammal Research Program, to assess dolphin presence through whistle detection at a sonar detonation sites off O'ahu, Hawai'i. Throughout her time at MLML, in addition to her thesis work, she conducted a passive acoustic study to determine acoustic behavior and repertoire composition of Risso's dolphin in the Monterey Bay. She enjoys education and outreach and has worked at the Monterey Bay National Marine Sanctuary as a volunteer coordinator and educator for more than three years. Driven by her passion for marine mammal acoustics she developed a K-12 program called "Listen up!" to educate kids about marine mammals and sounds in the ocean.

Thesis Abstract:
As apex predators, killer whales (Orcinus orca), can have large impacts on ecosystems through top-down predation. In the North Pacific, three genetically distinct ecotypes exist that differ in diet, range, morphology, and vocal behavior. Killer whales are known to occur in the Chukchi Sea but, few data exist regarding ecotypes present. Since killer whale ecotypes differ in vocal behavior, they can be distinguished based on call type, call rate, and bandwidth. An Autonomous Underwater Recorder for Acoustic Listening (AURAL) device was deployed 75 km off Point Hope, Alaska in the southeastern Chukchi Sea to identify which killer whale ecotypes were present in this region. A total of 1315 killer whale calls were detected on 38 days during the summers of 2013 to 2015. Calls were manually grouped into six categories based on the general call contours: multi-part, downsweep, upsweep, modulated, single modulation and tonal. The majority of detections were tonal calls (n = 607, 46%), and multi-part calls (n = 351, 27%) that contained high frequency and low frequency components. Comparison of the current call dataset with published literature showed similarities in peak frequency with other transient populations. These results indicate occasional presence of transient killer whales in the southeastern Chukchi Sea. This study provides the first comprehensive, catalogue of transient killer whale vocalizations in this region.
