Biophysical drivers of vigorous carbon cycling near the Kuroshio Extension
Approximately seven years of daily-averaged autonomous CO2 observations from NOAA’s Kuroshio Extension Observatory surface mooring were used to close the mixed-layer carbon budget, finding high rates of net community production during the spring bloom period.
Climate sensitivity in models consistent with energy budget constraints
Equilibrium climate sensitivity (ECS) — defined as the near-surface air temperature change that would result from a doubling of atmospheric CO2 — is a key metric of climate change. New findings suggest that the ECS from global energy budget constraints is in agreement with values derived from other methods and simulated by global climate models.
Warm eddies in Caribbean Sea could be a link to tropical cyclone intensification
A recent study highlights results obtained from an aircraft ocean survey that targeted a large warm core eddy in the eastern Caribbean Sea, where upper ocean measurements are crucial to understanding the complexities of heat and moisture transfer during the passage of tropical cyclones.
Coastal warming related to ‘the Blob’
New research shows the extent and development of 'the Blob' using satellite surface temperature data to reveal warm temperature anomalies appearing as early as March 2014 in the central and southern California coast, and eventually extending to the entire West Coast and dissipating in August 2016.
Multidecadal Indian Ocean variability linked to the Pacific
In a new paper from Journal of Climate, researchers show that changes in the Indian Ocean subsurface heat content over the last 50 years can be linked to Pacific Ocean variability associated with the Pacific Decadal Oscillation/Interdecadal Pacific Oscillation.
Deep southeast Indian Ocean waters see accelerated freshening
A recent investigation has shown that in the abyssal southeast Indian Ocean the Antarctic Bottom Water (AABW) freshening and warming have changed over the last decade. After a third full repeat of line IO8S in the region, GO-SHIP observations suggest strongly accelerated AABW freshening since 2007.
