Researchers from the University of British Columbia (UBC) have uncovered compelling evidence of a potentially new population of killer whales in the Northeastern Pacific, distinct from known orca ecotypes. 

This discovery, documented in a recent study published in Aquatic Mammals, is based on observations of 49 orcas exhibiting unique hunting behaviours, including predation on sperm whales and sea turtles, off the coasts of California and Oregon.

The Michigan Shipwreck Research Association (MSRA) has uncovered the remarkably preserved steamship Milwaukee, which vanished in 1886 after a collision and has been resting in 360ft (100m) of water for over a century.

MSRA located the Milwaukee in June 2023 using side-scan sonar and documented it extensively with an ROV. Still, the discovery was only revealed to an enthralled audience in a live announcement during their annual film festival.
