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:

Satellites help spot whales

Scientists have demonstrated how new satellite technology can be used to count whales, and ultimately estimate their population size. Using Very High Resolution (VHR) satellite imagery, alongside image processing software, they were able to automatically detect and count whales breeding in part of the Golfo Nuevo, Peninsula Valdes in Argentina.

A changing climate will make species homeless


The survival of all species on land and sea depends on them living within a set range of temperatures, but local climates are shifting. Species have to adapt, or move, or face extinction.


In a new study published today, a team of international scientists shows how fast and in which direction local climates have already shifted. This is important for anticipating the future. The research also highlights vulnerable areas, which will help focus conservation efforts.
