WW2 LIberty ships became succesful artificial reefs

During the war, more than 2,750 Liberty ships were built by the US to help crush the Japanese and German war machines by delivering cargo, troops and munitions.

In the mid-1970s some of the vessels were stripped and deliberately scuttled to create fishing reefs, and that initial success led to an inshore and offshore artificial reef program that continues today..

Holy Sidemount!

This of course makes for good copy for the uninitiated—diving companies have long used tech sizzle to sell gear and training to recreationalists—but the fact is, it’s a bit of marketing hyperbole.

WW2 German seaplane to be salvaged in Norway

On 26th December 1942 when Norway was occupied by German forces, a Heinkel 115B seaplane from the Küstenfliegergruppe 906 based at Sola, sets down on Hafrsfjord when one of the floats tears off, capzing the plane.

The crew is rescued and so is one of the engines but the plane sinks to the seabed where it lies forgotten for almost seven decades until it was accidentally rediscovered when the Norwegian Charting Authorities were testing new sonar equipment.

Fish follow the leader

"Actually having good followers helps leaders get on with their tasks," said Andrea Manica, an evolutionary biologist at the University of Cambridge who led the study recently published in the journal Current Biology. "They were doing more together than they would be doing by themselves."

Manica and his colleagues monitored individual threespine sticklebacks (Gasterosteus aculeatus) for their willingness to leave their safe, weedy cover and venture out into the risky, open waters to feed -- an indication of fish temperament.

Elphinstone: Grand Canyon of Southern Egypt

It was 6:30 in the morning, and my dive buddy and I were hauling our gear back from the big zodiac speedboat after a thrilling midnight dive on the famous Elphinstone reef in the Red Sea near Marsa Alam, Egypt. While rinsing my gear, Ahmed—the local dive guide—started talking to me because I was diving a back plate, wing and long hose just like him, and he probably felt some kind of connection.

Giant Mantas of Equador

There is a recently developed term making its way into common use amongst the wider dive community, and that term is, citizen scientist. The science community is waking up to the fact that the common man and woman are valuable resources for acquiring many missing pieces in the jigsaw puzzle that is marine research, particularly for migratory species
