Starting today, there will be a new sentinel keeping constant watch over the ocean and atmosphere here in this inhospitable environment. We are deploying the surface mooring, also known as SUMO, to replace the mooring that was deployed last year but which mysteriously disappeared in October. That story will be the subject of a future blog post.

DOI: 10.5067/SPUR2-MOOR2: Short Name: SPURS2_MOORING_PICO: Description: The SPURS (Salinity Processes in the Upper Ocean Regional Study) project is a NASA-funded oceanographic process study and associated field program that aim to elucidate key mechanisms responsible for near-surface salinity variations in the oceans.


The mooring uses a 3m diameter surface buoy and over 6km of mooring line to provide the compliance needed to ride massive waves in the southern ocean. We configured the entire mooring in ProteusDS and ran through the three steps to determine maximum loads at the top of the mooring, next to the buoy.

A Brief Introduction to Important Vessel Mooring Techniques

One example is with the Sentinel-3 satellite, which carries the ‘Ocean and Land Cover Instrument’ (OLCI) . This instrument has 21 bands in the range of 0.4–1.02 μm, but Sentinel-2 also carries the Sea and Land Surface Temperature Radiometer (SLSTR) that comprises nine bands in the spectrum of 0.55–12 μm [7].
