A team of UK and French scientists have shown dramatic changes in the abundance of phytoplankton in the North Atlantic over the last 60 years driven primarily by climate variability and North Atlantic warming. In particular, the scientists focused on the important group of phytoplankton collectively known as diatoms. This major phytoplankton group contributes approximately […]
Much of the “excess heat” stored in the subtropical North Atlantic is in the deep ocean (below 700m), new research suggests. Oceans have absorbed about 90% of warming caused by humans. The study found that in the subtropical North Atlantic (25°N), 62% of the warming from 1850-2018 is held in the deep ocean. The researchers […]
FASTER SOUND TRANSMISSION IN THE OCEANS DUE TO CLIMATE CHANGE WILL CHANGE THE UNDERWATER SOUNDSCAPE MARINE ORGANISMS RELY ON FOR SURVIVAL AND REPRODUCTION IN COMING DECADES. Climate change will significantly alter how sound travels underwater, potentially affecting natural soundscapes as well as accentuating human-generated noise, according to a new global study that identified future ocean […]
Coccolithophores are microscopic algae that form tiny limestone plates, called coccoliths, around their single cells. The shape and size of coccoliths varies according to the species. After their death, coccolithophores sink to the bottom of the ocean and their coccoliths accumulate in sediments, which faithfully record the detailed evolution of these organisms over geological time. […]
A new international study carried out by the Institute of Environmental Science and Technology of the Universitat Autònoma de Barcelona (ICTA-UAB) has examined the distribution of biomass across all life in the oceans, from bacteria to whales. Their quantification of human impact reveals a fundamental alteration to one of life’s largest scale patterns. As policymakers […]
