Ocean Net Heat Flux Influences Seasonal to Interannual Patterns of Plankton Abundance
Changes in the net heat flux (NHF) into the ocean have profound impacts on global climate. We analyse a long-term plankton time-series and show that the NHF is a critical indicator of ecosystem dynamics. We show that phytoplankton abundance and diversity patterns are tightly bounded by the switches between negative and positive NHF over an annual cycle. Zooplankton increase before the transitio...
متن کاملSurface flux and ocean heat transport convergence contributions to seasonal and interannual variations of ocean heat content
We present an observation-based heat budget analysis for seasonal and interannual variations of ocean heat content (H) in the mixed layer (Hmld) and full-depth ocean (Htot). Surface heat flux and ocean heat content estimates are combined using a novel Kalman smoother-based method. Regional contributions from ocean heat transport convergences are inferred as a residual and the dominant drivers o...
متن کاملSeasonal to interannual upper-ocean variability in the Drake Passage
Year-round monitoring of the upper-ocean temperature variability in Drake Passage has been undertakensince September 1996 through repeat expendablebathythermograph(XBT) surveys. The closely spaced measurements (6–15 km apart) provide the rst multi-year time series for examining seasonal to interannual variability in this Southern Ocean choke point. While the temperature sections reveal the se...
متن کاملRole of Net Surface Heat Flux in Seasonal Variations of Sea Surface Temperature in the Tropical Atlantic Ocean
The present study used a new net surface heat flux (Qnet) product obtained from the Objective Analyzed Air–Sea Fluxes (OAFlux) project and the International Satellite Cloud Climatology Project (ISCCP) to examine two specific issues—one is to which degree Qnet controls seasonal variations of sea surface temperature (SST) in the tropical Atlantic Ocean (20°S–20°N, east of 60°W), and the other is ...
متن کاملSeasonal and interannual variations of upper ocean heat balance off the west coast of Australia
[1] The Leeuwin Current, a warm, poleward flowing eastern boundary current, dominates the surface circulation off the west coast of Australia and has profound influence on regional marine ecosystem and fisheries recruitment. In this study, the seasonal and interannual variations of upper ocean heat balance in the Leeuwin Current region are analyzed by using an eddy-resolving numerical model sim...
