Corals don’t lie: centuries of rising sea levels and temperature data revealed

AIMS scientists together with a team from The University of Western Australia, CSIRO and the University of San Diego have analysed coral cores from the eastern Indian Ocean to understand how the unique coral reefs of Western Australia are affected by changing ocean currents and water temperatures. The research was published today in the international journal Nature Communications. The findings give new insights into how La Niña, a climate swing in the tropical Pacific, affects the Leeuwin current and how our oceans are changing.

Autonomous sub dives for marine science

Donegal, 29 March, 2014 -- A cutting edge, unmanned submarine was launched today off Donegal on a 30-day scientific mission to investigate the marine environment of the little-known slopes of the ocean shelf edge.


Fitted with the latest oceanographic sensors, battery technology and advanced satellite communication, Autosub Long Range (ALR) is a state-of-the-art autonomous underwater vehicle (AUV) developed by the National Oceanography Centre for collecting scientific data for a four-year research programme studying the water exchange between the UK’s shelf edge seas and the deep ocean. The shelf edge is where the shallow coastal waters of the UK’s continental shelf meet the deep ocean water across the steep sloping sides of the shelf edge. This area is nutrient-rich, productive, important for fisheries and is open to a lot of movement and exchange of water and nutrients.

Increasing acidity and rising temperatures will have complex effects on marine diseases in coral reefs

Coral reefs today face many threats: increasingly acidic oceans, rising temperatures, over-fishing, and pollution, to name a few. As if these pressures weren’t enough, corals and the animals that live on them can get sick, just like humans, and ocean acidification, global warming, and pollution may make reefs more vulnerable to disease.

Large-scale toxic red tides plague eastern and southern coasts of South Africa

The coastal areas between East London and Wilderness have been subjected to the largest, and most persistent, red tide in recorded history. The red tide first made its appearance in mid-December at several coastal locations simultaneously and grew in size to cover more than 300 km of coastline (see satellite chl-a image below).

Publications about capacity building in marine science

Training opportunities in marine science have been the topic of articles published in peer-reviewed journals recently, reiterating the importance and need for capacity building in this arena. They include papers in Marine Pollution Bulletin and Eos and can be seen in the following articles:
