Aliased Tidal Variability in Mesoscale Sea Level Anomaly Maps

Mesoscale Variability in the Labrador Sea

My immediate objective is to understand the interactions between convection and mesoscale circulation, in order to quantify the in uence of convective events on the large scale circulation. Such interactions include: (a) The lateral mixing generated by baroclinic instability and geostrophic eddy interactions. How e cient are lateral mixing processes in convective regions? Can these processes ac...

Mesoscale variability in the metabolic balance of the Sargasso Sea

Net community production (NCP) experiments based on in vitro changes in dissolved oxygen were carried out in three mesoscale eddies investigated in the Sargasso Sea in the summer of 2004. NCP estimates ranged from negative to positive values, and the age and type of the sampled eddy were important factors responsible for this variability. Positive rates occurred in younger cyclones and in areas...

Geographic Variability of Sea-Level Change

Local sea-level changes differ significantly from global-mean sea-level change as a result of (1) non-climatic, geological background processes; (2) atmosphere/ocean dynamics; and (3) the gravitational, elastic, and rotational “fingerprint” effects of ice and ocean mass redistribution. Though the research communities working on these different effects each have a long history, the integration o...

Low-frequency Atlantic sea level variability

The control run of the Hadley Centre-coupled climate model (HadCM3) is used to establish the sources of multidecadal/ centennial sea level (SL) variations in the northwest Atlantic. It is shown that variations in the sea level for the largest part of this area are related to variations in the thermohaline structure of the upper (c 500 m) part of the ocean. Temperature variations dominate steric...
