Ocean Acidification and Other Ocean Changes

The world’s oceans have absorbed about 93% of the excess heat caused by greenhouse gas warming since the mid-20th century, making them warmer and altering global and regional climate feedbacks. Ocea[...]

The Magnitude of Global Marine Species Diversity

The question of how many marine species exist is important because it provides a metric for how much we do and do not know about life in the oceans. We have compiled the first register of the marine s[...]

The Colors of Carbon

A full spectrum of colour-based descriptions has emerged to describe the properties and distribution of organic carbon: black, brown, red, blue, green and teal. This colour-based terminology contribut[...]

Seagrass ecosystems as a globally significant carbon stock

The protection of organic carbon stored in forests is considered as an important method for mitigating climate change. Like terrestrial ecosystems, coastal ecosystems store large amounts of carbon, an[...]

Keys to Successful Blue Carbon Projects: Lessons learned from global case studies

Ecosystem services such as protection from storms and erosion, tourism benefits, and climate adaptation and mitigation have been increasingly recognized as important considerations for environmental p[...]

Seagrass Community Metabolism: Assessing the carbon sink capacity of seagrass meadows

The metabolic rates of seagrass communities were synthesized on the basis of a data set on seagrass community metabolism containing 403 individual estimates derived from a total of 155 different sites[...]

Status and Trends for the World’s Kelp Forests

Kelp forests are extensive underwater habitats that range along 25% of the world’s coastlines, providing valuable resources, habitat, and services for coastal communities. They grow best in cold, nu[...]

Seasonal and Temporal CO2 Dynamics in Three Tropical Mangrove Creeks: A revision of global mangrove CO2 emissions

Continuous high-resolution surface water pCO2 and δ13C-CO2 and 222Rn (dry season only) were measured over two tidal cycles in the wet and dry season in three tropical tidal mangrove creeks on the nor[...]
