A new study by an international team of researchers led by the University of Auckland has found that whales in Auckland’s Hauraki Gulf consume around 3 million microplastics every day. The researchers estimated microplastic exposure from prey and scats of whales using a stochastic simulation model, which led to the estimated daily ingestion rate of microplastics. […]
A group of researchers from Stanford University has published a new paper on prey consumption of baleen whales. Previous studies on prey consumption of large marine animals have used metabolic models. Here, the research group used tags deployed on seven baleen whale species in conjunction with acoustic measurements of prey density to calculate prey consumption at daily to annual […]
A new webinar, hosted by National Marine Sanctuaries (NOAA), will be held on 3rd November 2021 and will focus on the findings of two international studies highlighting Humpback whales’ use of the Ocean basin. Date/Time: November 03, 2021 at 12pm Hawai`i | 3pm Pacific | 6pm Eastern Presented by: David Mattila, Secretariat to the International Whaling Commission […]
A new paper from the Ocean Modeling Forum’s Working Group on Marine Mammal Bycatch provides a summary on the various methods available for assessing the abundance of pinnipeds, cetaceans, and sirenians. Authors discuss key issues, including: General principles in estimating abundance Methods for estimating abundance and their strengths and weaknesses in relation to practical issues […]
The research team behind the recently published study “Ocean Regime Shift is Driving Collapse of the North Atlantic Right Whale population” are hosting a free-to-attend webinar on Wednesday 13th October 2021 at 13:00 ET. Titled “How Climate-Driven Ocean Changes are Further Threatening North Atlantic Right Whales”, the webinar will discuss the threats faced by North […]
Warming oceans have driven the critically endangered North Atlantic right whale population from its traditional and protected habitat, exposing the animals to more lethal ship strikes, disastrous commercial fishing entanglements and greatly reduced calving rates. Without improving its management, the right whale populations will decline and potentially become extinct in the coming decades, according to […]
A new collaborative study provides new insight into how two species of minke whales utilize the Caribbean and neighboring Atlantic waters throughout their life cycle. The findings add further conservation value and significance to the relatively new Yarari marine sanctuary of the Netherlands. By combining scientific, citizen science and public information, this study provides key […]
Advances in biologging technology have allowed researchers the ability to quantify the underwater movements and behaviors of marine mammals in novel ways. By incorporating motion sensors with remote, concurrent oceanographic sampling, the ability to contextualize the foraging behavior and performance of marine mammals can now be accomplished.
