California

The Shark Lab at Cal State Long Beach is in danger of running nearly out of funds and may have to shut down programs that protect Southern California beachgoers.

Long Beach Shark Lab May Lose Funding

For years, the Shark Lab at California State University, Long Beach, has been at the forefront of research, tracking shark movements and behaviour, which has been crucial for beach safety and conservation efforts. The loss of funding could severely hinder these vital studies, potentially impacting both ecological understanding and public welfare.

The remarkable sighting occurred on 9 July 2023, approximately 400m (1,300ft) off the shores of Carpinteria, California. Wildlife filmmaker Carlos Gauna and Phillip Sternes, a doctoral student in the Department of Biology at the University of California Riverside, stumbled upon the extraordinary sight while filming aerial footage.

White sharks complicate population recovery for sea otters

Complex interactions and conflicts between protected populations may challenge the recovery of whole ecosystems. Several factors indicate that white sharks may be currently limiting the recovery of California sea otters.

Protected white sharks (Carcharodon carcharias) and pinnipeds have an established predator–prey relationship along the California coast.

White sharks are considered threatened by the IUCN Red List, and though they are protected at state, federal, and global scales, their current status in the northeastern Pacific is debated.

Hydrothermal vents and possible new species discovered in Gulf of California

The hydrothermal vents are located in the Pescadero basin and are unique both in their chemistry and appearance to other known hydrothermal vents, as they are the only ones currently observed to emit clear fluids as opposed to dark, smokey fluids associated with iconic “black smoker” vents.

The largest of the new vent mounds, named Maija awi, sits midway between the JaichaMaa ‘ja’ag vent field, discovered by the same team during Schmidt Ocean Institute’s 2018 R/V Falkor expedition, and the Auka vent field, discovered during an expedition by the Monterey Bay Aquarium Research Institute (MBARI) in 2015.

Business rivals worked together to make Dana Point a Whale Heritage Site

In late January 2021, the World Cetacean Alliance (WCA) named Dana Point, California as a Whale Heritage Site, the first such site in the Americas.

The reasons were obvious: As one of the world's top whale-watching destinations, it hosts a variety of whales all year round, including the blue whale. It has more dolphins per square mile than anywhere in the world. Dana Point also has a small non-commercial harbor, community support, and undertaken public outreach and education, advocacy and research efforts. 

Long Beach Scuba Show 2021 Cancelled

Last year, we told you that there was "no way to responsibly hold an event of this size with people from around the world for the foreseeable future." When we wrote that, we never would have guessed the "foreseeable future" would extend well over a year.

To bridge the gap, we are working on a resource for divers - for you. Information from our exhibitors with videos, specials, new products, travel and more.

Increases in California harbor porpoise population due to gillnet ban

Before they were closed down, these fisheries would cause the deaths of many harbor porpoises, as they ended up as bycatch in the fisheries' gillnets. And based on the numbers, it is apparent that such coastal set gillnets had taken a greater toll on the harbor porpoises than we realized.

This is the finding of a paper published in the Marine Mammal Science journal.

Giant kelp (Macrocystis pyrifera) is a species of kelp (large brown algae)

Kelp forests help the climate

Kelp is an ecologically and economically important foundation species in California, where forests line nutrient-rich, rocky bottom coasts. It also might alleviate acidification caused by too much atmospheric carbon being absorbed by the seas.

A new interdisciplinary analysis of giant kelp in Monterey Bay off the coast of California shows that near the ocean’s surface, the water was less acidic, suggesting the kelp canopy does reduce acidity.
