Underwater volcano behavior captured by timely scientific expedition
Researchers got a rare opportunity to study an underwater volcano in the Caribbean when it erupted while they were surveying the area. The research, published online in the journal Geochemistry, Geophysics, Geosystems, a journal of the American Geophysical Union, provides new insight into the little-studied world of underwater volcanoes. It investigated a volcano named Kick-‘em-Jenny (KeJ), which is thought to be named after the turbulent waters nearby.

Evidence of surprising ocean warming around Galápagos corals
The ocean around the Galápagos Islands has been warming since the 1970s, according to a new analysis of the natural temperature archives stored in coral reefs.

American lobsters feeling the heat in the northwest Atlantic
Rising temperatures along the bottom of the Atlantic Ocean will force American lobsters farther offshore and into more northern waters, a new study finds. Climate models project that ocean bottom temperatures in the Atlantic along the U.S. East Coast may rise by up to 4.3 degrees Celsius (7.7 degrees Fahrenehit) by the end of the century. The new study’s results show these rising temperatures will likely make conditions in the American lobster’s southernmost range—less hospitable in the future for juveniles, pushing them farther north and into habitats farther offshore.

Proteins in shark teeth could hint at what they eat
Certain molecules found in shark teeth proteins could tell scientists how the predators are connected to other animals in the food web, according to new research.

Earwax like ice cores: Unlocking the past hidden in whale earplugs
Data collectors are cruising around oceans worldwide, following blooms of productivity and accumulating decades of information—all from earwax. New research shows whale earplugs provide records of the animals’ movements and diets over the course of their long lives.

Scientists counter threat of flooding on coral reef coasts
Scientists have developed a computer simulation tool to predict short-term flood hazards on coral-reef-lined coasts and to assess longer-term impacts from climate change. The assessments will give input to estimate societal or economic risk and damage from such flooding.

Rising sea levels could weaken coral reefs’ protective influence on Brazil’s coast
Rising sea levels could diminish the ability of Brazil’s coral reef systems to weaken incoming ocean waves, resulting in stronger waves hitting populated areas on the Brazilian coastline, according to new research.

Scientists may have solved mystery of rapidly rising Indian Ocean sea level
Sea levels around the world have risen by 1.7 millimeters (0.07 inches) on average each year since 1880, but in recent years, scientists have observed a rapid increase in sea level in the north Indian Ocean. Tide gauge records and other datasets reveal the pace of sea level rise in the north Indian Ocean has accelerated to 3.1 millimeters (0.12 inches) per year within the last three decades. The accelerating sea level rise has confounded scientists but new research claims weakening of South Asian monsoons may be to blame.

Polluted groundwater eroding Hawaiian coral reefs, study shows
Local land-based pollution makes coral reefs more vulnerable to ocean acidification and could trigger coastal coral reef ecosystem collapses sooner than projected, according to new research.

The missing mass — what is causing a geoid low in the Indian Ocean?
In a recent study, scientists explored the reasons behind the existence of the Indian Ocean Geoid Low, a point of low gravity found just south of the Indian peninsula.
