A Closer Look at Human-Shark Encounters

A recent article by Sam Fletcher begins with the gripping account of a wildlife videographer, Scott Fairchild. Using a drone, he captures a heart-stopping moment when a great white shark repeatedly approaches a lone swimmer off the coast of San Diego. Yet suddenly the shark veers away and disappears. Fairchild states that he has seen countless such encounters between swimmers and white sharks off the Californian coast.

Juvenile Great White Sharks Prefer Shallow Water

The groundbreaking study delved into the drivers behind how juvenile white sharks move. Using special tracking technology that listens to the sharks and tracks their positions, the team of scientists, led by Emily Spurgeon, gathered detailed information about how the varying temperatures of the layers of the sea affect their travels.

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.
