SPURS Pasadena WorkshopSPURS-1 SynthesisSPURS-2 Planning

April 16-18, 2014

Del Mar Meeting Room, Courtyard Marriot

Background• Jan. 2013 SPURS meeting in Miami chose

an eastern tropical Pacific focus for Fresh SPURS-2

• Miami and Ocean Sciences Meeting in Feb. 2014 provided looks at SPURS-1 results

• NASA Synthesis and Planning proposals submitted in December are being funded (funds available soon)

• This meeting is to facilitate both the synthesis and planning

• Immediate need is for SPURS-2 “white paper”, in preparation for July 1 proposals.

Synthesis Goals

• Resolve terms of the freshwater and heat budgets of the upper 1000m on time scales of a few days and spatial scales of 100-1000 km around the salinity maximum

• Identify/Quantify processes responsible for ~100m winter mixed layer, restratification in spring and relation to subsurface salinity maximum.

• Provide detailed description/analysis of near-surface T and S fields during annula cycle and role in air-sea interaction and remote sensing.

SPURS-2

• Eastern Tropical Pacific – bookend to SPURS-1, as Atlantic water is carried into the Pacific across Central America

• Fresh water forcing poses different issues than evaporation, more surface focused and barrier-layer physics, rather than subduction

SPURS-2• May - 2014: Develop planning document for

NASA and participant review

• July 30 – SPURS-2 Proposals due at NASA

• Aug 16 – Proposals due at NSF

• ~Oct30 SPUR-2 NASA Funding Decisions

• Jan 2015 NASA Funding starts

• Spring 2015 SPURS-2 Workshop

• 3rd qtr 2015 -1st qtr 2015 – First cruise
