Marine Snowfall at the Equator

GEOMAR team publishes a detailed picture of the biological particle flow into the deep sea along the equator. Animal excrements and parts of dead organisms constantly sink from the surface of the oceans towards the deep sea. This particle flow, also referred to as “marine snowfall”, plays an important role in the global carbon cycle and consequently for the climate. Little is known so far about its distribution in the water column.

Scientists to visit hidden Antarctic ecosystem after giant iceberg calving

A team of scientists, led by British Antarctic Survey (BAS), is planning an urgent mission to investigate a mysterious marine ecosystem that’s been hidden beneath an Antarctic ice shelf for up to 120,000 years.  The researchers want to discover how this marine ecosystem will respond to environmental change in a climate-sensitive region.

 

Antarctic marine life may grow faster in a warming world

British Antarctic Survey Press release - 31 August 2017

A team of scientists has discovered that a 1°C rise in local sea temperature has massive impacts on an Antarctic marine community. These new results are published this week (31 August) in the journal Current Biology, and enable researchers to better understand the biological implications of the future ocean warming predicted by the Intergovernmental Panel on Climate Change (IPCC).

 

Coral reef connections

Scientists have identified how coral reefs, hundreds of miles apart, are connected by ocean currents. Observing these networks from space may prove vital for their conservation.

Marine microplastics detected in bottom-dweller bellies for the first time

Around half of marine creatures living at depths of more than 2,000 metres in the North Atlantic could be eating microplastic material, marine scientists have discovered.

 

Researchers at the Scottish Association for Marine Science (SAMS) in Oban, Scotland sampled deep-sea starfish and sea snails from the Rockall Trough and found microscopic traces of plastic in 48 per cent of those sampled. The levels of plastic ingestion were comparable to those found in species living in shallower coastal waters.
