Marine heatwaves decimate sea urchins, mollusks and more at Rottnest
Curtin University researchers believe rising sea temperatures are to blame for the plummeting number of invertebrates such as mollusks and sea urchins at Rottnest Island off Western Australia, with some species having declined by up to 90 percent bet.....»»
Light pollution threatens coastal marine systems, study suggests
Artificial light at night has a profound effect land-based life—from birds to fireflies to humans. But a new study suggests we need to widen our view to include light pollution's effect on coastal marine ecosystems, impacting everything from whales.....»»
New research predicts effects of marine heat waves on top ocean predators
Forecasts can now predict the location and onset of marine heat waves that can disrupt marine ecosystems. Scientists say the next step is to forecast what happens to top predators that inhabit those ecosystems......»»

NASA scientists test new tool for tracking algal blooms
By the time they were over, a series of massive algal blooms along the west coast of Florida in 2020 would be linked to some 2,000 tons of dead marine life around Tampa Bay. The human costs were stark, too, including a double-digit increase in asthma.....»»
Why do female great hammerhead sharks gather every summer in French Polynesia?
A large international team of marine scientists are trying to solve the mystery of why a large group of female hammerhead sharks have gathered in two French Polynesian atolls every summer of over the past decade. In their paper published in the journ.....»»
Marine heat waves don"t just hit coral reefs. They can cause chaos on the seafloor
Most of us know what a heat wave feels like on land—sweltering heat for days. But oceans get heat waves too. When water temperature goes over a seasonal threshold for five days or more, that's a marine heat wave. They do their worst damage in summe.....»»
Team develops novel sponge-based triboelectric nanogenerator for corrosion protection in transportation systems
Corrosion causes significant losses to various industries. Cathodic protection is used to protect steel in marine industries. Triboelectric nanogenerators (TENG) converts mechanical energy into electricity based on triboelectrification and electrosta.....»»

Tides may be responsible for up to 69% of under-ice melting in an Antarctica ice shelf
The ice shelves—the marine-terminating glaciers of the Antarctic Ice Sheet—are melting, and it's not just because of rising atmospheric temperatures. In a one-two punch, ice shelves in Antarctica are fighting a losing battle against rising temper.....»»
Motion-sensing cameras set up along protected California shoreline show impact of coyotes on intertidal habitats
