Software Package for an Adaptive Satellite-based Sampling for Oceanographic cruises

The temporal and spatial variability of the horizontal mesoscale and submesoscale circulation strongly affect marine environment fields and biogeochemical budgets and this represents a real challenge during in situ measurements. Indeed, samplings which are only few tens of kms or few weeks apart may be representative of very different situations.
The software package SPASSO (Software Package for an Adaptive Satellite-based Sampling for Oceanographic cruises) has been developed to overcome this problem. SPASSO diagnostics are based on NRT acquisition of satellite altimetry and ocean color and on model predictions.

SPASSO provides maps of dynamical and biogeochemical structures such as fronts, eddies and filaments, in addition to chlorophyll and SST, which are automatically generated. SPASSO can be used in Delayed Time (DT) for providing products in a region of interests or else for performing a systematic multi-field DT analysis of a region at various scales. SPASSO is used to guide the in situ sampling strategy as well as the interpretation of collected observations. This adaptive strategy based on these diagnostics has been applied during several ocean campaigns since 2010.

Use of SPASSO for an adaptive sampling strategy during SWOT-AdAC campaigns

SWOT-AdAC Consortium members can get in touch with SWOT-AdAC Science Officer Louise Rousselet (louise.rousselet@mio.osupytheas.fr) which will support  their in situ campaigns to compare results from different sites and develop near real-time sampling strategies.
