Respiration Quotient Variability and Ocean Oxygen Levels

by Eileen Hofmann 1 November 20221 November 2022

Respiration quotients in the Atlantic and Pacific Oceans reflect different water temperature, nutrient stress and phytoplankton community structure, important for regional carbon and oxygen cycling.

Surface Temperature Sets the Pace of Sea Level Rise

by Christopher Piecuch 31 October 202221 February 2023

Reining in global mean sea level rise from land-ice wastage and ocean thermal expansion requires reducing global mean surface temperatures to near-preindustrial values.

Ozone, Water Vapor and Temperature: It’s a Complex Relation

by Germán Martinez 28 September 202227 September 2022

Solar occultation observations from the ACS/MIR instrument provide coincident profiles of O₃, H₂O and temperature, shedding light on correlations and unveiling knowledge gaps in Mars’s photochemistry.

A bright red, orange, and yellow thermal image of London and the surrounding area maps hotter and cooler areas of the city. The center of the image is the city of London, which is yellow, indicating that it is hotter than surrounding suburbs, which appear in varying shades of orange and red. The suburbs tend to become cooler, and appear darker red, moving toward the edges of the image. The River Thames snakes from right to left across the center of the image. It and several water reservoirs to the left of center are black, indicating that they are much cooler than the neighboring land.

Unchecked Ocean Warming Threatens Many Gulf and Caribbean Corals

by Rachel Fritts 23 September 202223 September 2022

Gulf of Mexico and Caribbean sea surface temperatures could surpass coral bleaching thresholds in the region as soon as 2050, motivating the need for prompt mitigation, researchers say.
