Ocean acidification may be impacting coral reefs in the Florida keys
Researchers found that the limestone that forms the foundation of coral reefs along the Florida Reef Tract is dissolving during the fall and winter months on many reefs in the Florida Keys. The research showed that the upper Florida Keys were the most impacted by the annual loss of reef.

How much does groundwater contribute to sea level rise?
Land water, including groundwater extraction, contributes far less to sea level rise than previously thought, according to a new study.

Influence of sea-ice loss on Arctic warming is shaped by temperatures in the Pacific Ocean
The Arctic amplification phenomenon refers to the faster rate of warming in the Arctic compared to places farther south. Arctic amplification has been linked to a spike in the number of persistent cold spells experienced in recent years over Europe and North America.

Antarctic bryozoans give hints of environmental changes in oceans
Antarctic regions are natural laboratories to study biodiversity and the impact of climate change. In Antarctica, some marine ecosystems are particularly vulnerable to the ocean acidification due to an excess of carbon dioxide released into the atmosphere. Studying the Antarctic bryozoans, marine invertebrates that live in colonies and make mineralized skeletons, can create new views to understand the effects of global ocean acidification.

Forming fogbows: Study finds limit on evaporation to ice sheets, but that may change
Although the coastal regions of the Greenland Ice Sheet are experiencing rapid melting, a significant portion of the interior of that ice sheet has remained stable -- but a new study suggests that stability may not continue. Researchers found that very little of the snow and ice on the vast interior of the ice sheet is lost to the atmosphere through evaporation because of a strong thermal 'lid' that essentially traps the moisture and returns it to the surface where it refreezes.

What lies beneath West Antarctica?
New research provides the first look into the biogeochemistry, geophysics and geology of Subglacial Lake Whillans, which lies 800 meters (2,600 feet) beneath the West Antarctic Ice Sheet.

Ice loss accelerating in Greenland's coastal glaciers
Surface meltwater draining through and underneath Greenland's tidewater glaciers is accelerating their loss of ice mass, according to a new study that sheds light on the relationship between meltwater and subglacial discharge.

Sea-level rise summit coincides with flooding risks in south Florida due to the moon, high tides and inclement weather
Just as parts of South Florida are bracing for potential risks of flooding in low-lying areas due to the close proximity of the moon, high tides, sea-level rise and inclement weather, researchers are bringing together professionals from the private and public sectors to help identify solutions and develop adaptation pathways.

Deep-sea biodiversity impacted by climate change's triple threat
A new study found that vulnerability of deep-sea biodiversity to climate change's triple threat -- rising water temperatures, and decreased oxygen, and pH levels -- is not uniform across the world's oceans.

Widespread loss of ocean oxygen to become noticeable in 2030s
A reduction in the amount of oxygen dissolved in the oceans due to climate change is already discernible in some parts of the world and should be evident across large regions of the oceans between 2030 and 2040, according to a new study.

Rainwater may play an important role in process that triggers earthquakes
Rainwater may play an important role in the process that triggers earthquakes, according to new research. Researchers have identified the sources and fluxes of the geothermal fluids and mineral veins from the Southern Alps of New Zealand where the Pacific and Australian Plates collide along the Alpine Fault.

Algae disrupt coral reefs' recycling
Coral reefs--the world's most productive and diverse marine ecosystems--rely on a masterful recycling program to stay healthy. A new study explores how a process known as 'microbialization' destroys links in coral reefs' delicate food chain.

Ancient marine sediments provide clues to future climate change
Atmospheric carbon dioxide concentration was the major driver behind the global climatic shifts that occurred between 53 and 34 million years ago, according to new research.

Researchers discover fate of melting glacial ice in Greenland
A team of researchers has discovered the fate of much of the freshwater that pours into the surrounding oceans as the Greenland ice sheet melts every summer. They were surprised to discover that most of the meltwater found off the west coast of Greenland actually originated from ice on the east coast. Meltwater originating from the west coast of Greenland, on the other hand, is often kept pinned to the coastline by strong winds, which push it northward toward Baffin Bay.

Scientists discover new reef system at mouth of Amazon River
As large rivers empty into the world's oceans in areas known as plumes, they typically create gaps in the reef distribution along the tropical shelves--something that makes finding a reef in the Amazon River plume an unexpected discovery.

Water color, phytoplankton growth in the Gulf of Maine are changing
The amount of dissolved organic carbon from rivers emptying into the Gulf of Maine has increased over the last 80 years, a trend they predict will continue through 2100 if annual precipitation continues to increase, warn researchers. Runoff is changing the color of the seawater, reducing the light available to phytoplankton for photosynthesis, causing a decline in overall productivity.

The Arctic is facing a decline in sea ice that might equal the negative record of 2012
Sea ice physicists are anticipating that the sea ice cover in the Arctic Ocean this summer may shrink to the record low of 2012. The scientists made this projection after evaluating current satellite data about the thickness of the ice cover.
