A new study reveals how manta rays form unique interactions with other fishes in South Florida waters—highlighting their complex ecological interactions between species that support ocean life.

Harvard engineers, as part of Project CETI, have built an open-source bio-logger that adheres to sperm whales and records high-fidelity, multi-channel audio plus rich behavioral and environmental data. The data are tailored for machine learning analysis so that researchers can better understand whale communication.

An international team of researchers led by the Max Planck Institute for Marine Microbiology has uncovered a hidden world of tiny partnerships thriving in wastewater treatment plants worldwide. The microscopic allies—specialized bacteria living inside single-celled hosts—play a surprising role in both cleaning water and potentially contributing to greenhouse gas emissions.

Ocean data assimilation systems combine data assimilation with numerical ocean models to predict ocean conditions. Researchers recently created the Yin-He Global Ocean Data Assimilation and Forecast System (YHGO) to provide more accurate estimations of oceanic conditions than older platforms.
