Sentences with phrase «sparse ocean observations»

Gridding sparse ocean observations onto a very high (in this case, 1 - by - 1 degree latitude x longitude) resolution is prone to producing some apparent structures that are simply artifacts of mathematical interpolation, even when isopycnal methods are utilised (this is common for gridding of data).

Not exact matches

Temperature observations are sparse around the hostile continent, but scientists recently modeled the ocean current knock - on effects of these wind changes, which have been caused by ozone thinning and by the buildup of greenhouse gases.
However, these observations are decidedly sparse in the deep sea and need to be enhanced, through sustained deep - ocean observing (e.g., via Deep Argo).
Here the adjustment is determined by (1) calculating the collocated ship - buoy SST difference over the global ocean from 1982 - 2012, (2) calculating the global areal weighted average of ship - buoy SST difference, (3) applying a 12 - month running filter to the global averaged ship - buoy SST difference, and (4) evaluating the mean difference and its STD of ship - buoy SSTs based on the data from 1990 to 2012 (the data are noisy before 1990 due to sparse buoy observations).
Observations alone are too sparse in the oceans to describe and understand decadal and longer timescale variations in the ocean circulation and hence ocean heat uptake.
Earlier measurements had lowballed heat accumulation due to historically sparse observations for large parts of the ocean.
While sea ice thickness observations are sparse, here we utilize the ocean and sea ice model, PIOMAS (Zhang and Rothrock, 2003), to visualize mean sea ice thickness from 1979 to 2018.
Estimates for the deep Southern and Abyssal Oceans are by Purkey and Johnson (2010) based on sparse observations.
This way we are able to partly overcome the difficulty associated with sparse subsurface ocean observations in the past.»
Such field measurements are sparse, however, and the record of remotely sensed ocean color observations — the chief source of global biogeochemical data today — is limited to the sea surface and does not include a number of key variables.
