(a) Correlation between the NEUC transport and the SST and pseudo-wind stress in the Tropical Atlantic. The boxes are regions of high magnitude of correlation, where a SST index (SST2) and a meridional wind index (y-wind2) are taken (b). (c) Lagged correlation between the indices timeseries and the NEUC transport index. Image Credit: NOAA AOML.

Relationship between the Off-equatorial Current System and the Tropical Atlantic Variability

Scientists at PHOD developed a synthetic method, which combines high-density expendable bathythermograph (XBT) temperature data along the AX08 XBT transect (which runs between Cape Town and NYC) with altimetric sea level anomalies, to estimate the variability of the off-equatorial currents, such as the North Equatorial Countercurrent and the North Equatorial Undercurrent, on seasonal to interannual timescales. Understanding how the ocean dynamics is liked to anomalies of temperature and wind-stress in the tropical Atlantic is critical to understand the climate and weather variability in the adjacent continental areas.

IPCC projected changes of bluefin tuna’s spawning habitat in the Gulf of Mexico due to anthropogenic global warming for three time frames: top (late 20th century), (middle) mid 21st century and (bottom) late 21st century. The colors indicate preferred spawning habitat, with yellow/orange for favored locations and blue/purple for non-ideal regions. Liu and Lee’s research indicates that the area of spawning habitat for the bluefin tuna may not be as drastically reduced as in the IPCC results shown in these figures. Image Credit: NOAA AOML.

Collaborative Research between PhOD and SEFSC Presented at Bluefin Tuna Workshop

A joint workshop hosted by NOAA and the National Aeronautics and Space Administration (NASA) for bluefin tuna research was held at the University of Miami on December 6-7th. Researchers with AOML’s Physical Oceanography Division (PhOD) presented the results of their collaborative efforts with NOAA’s Southeast Fisheries Science Center (SEFSC), which have focused on the link between the ocean and stock assessment species of relevant commercial importance.
