Coastal ocean acidification affected by eutrophication

Rising atmospheric carbon dioxide levels are causing increased acidification of the oceans, a recent study has found that carbon dioxide released form decaying algal blooms can accelerate this process.

Nonlinear shallow wave interactions may explain deadly tsunamis

"Waves can sometimes interact to yield ripples that are much taller than the simply added combined heights of their originating waves, a sign of what researchers call 'nonlinear interactions.' [...] In shallow waters, most of these unusually tall waves look like an X or a Y from above". These waves were thought to be rare in nature, however recent research has shown they are much more common. Similar interactions may apply on a larger scale with tsunamis.

Coastal sea level rise may be greater than previously thought

A new model has shown that sea level rise in some habitats (such as inlets and estuaries where river flow and rainfall become significant) may have been underestimated with previous models.
