Microorganisms are the engines that drive most marine processes. Ocean modelling must evolve to take their biological complexity into account. Marine microorganisms are crucial for ocean health.

Leopard seals are prehistoric, reptilian-looking marine predators often portrayed as scary villains in movies such as "Happy Feet" and "Eight Below," but little is known about their basic biology. The ...

Marine snow—a mixture of dead plankton, waste, mucus, and other organic material slowly sinking from the ocean’s surface—is an important, but poorly understood, part of the ocean carbon cycle. Credit: ...

Marine ecology encompasses the study of complex interactions among organisms and their environment in the world’s oceans. Central to advancing this field has been the adoption of stable isotope ...

Biological processes in seawater are dependent on the supply of a number of chemical elements that serve as nutrients and affected by others that may act as toxicants. Besides the major algal ...

As the world warms, sweeping changes in marine nutrients seem like an expected consequence of increased ocean temperatures. However, the reality is more complicated. New research suggests that ...

Limited understanding of basic ocean processes is hindering progress in marine carbon dioxide removal, with the on-going commercialization of some approaches 'premature and misguided'. Scientists now ...

Climate science is entering a phase of reassessment as new ocean data introduces nuances that challenge long-standing assumptions. While global temperatures continue to trend upward, researchers are ...
