Science Activities: Activities: CTD surveys in vicinity of floats and gliders, including water collection for phytoplankton, nutrients, and other biogeochemical variables; profiles of optical properties; deployment and retrieval of profiling floats to measure particle flux and aggregates; underway measurements of near-surface optical properties and other biogeochemical variables and aerosols. Exact location of CTD surveys will depend on location of floats and gliders (deployed in early April 2008).

Draft R/V Knorr cruise plan, 8 February 2008 29 April, depart Reykjavik and steam toward location of D'Asaro Lagrangian floats (2 floats) and Lee gliders (4 gliders). Intended location is vicinity of 60N, 20W, but actual location will depend on float/glider trajectory since their deployment in early April. Determine when and where the floats will surface (note: each float surfaces every 36 h). Determine where to deploy Checkley SOLOPC floats and Lampitt APEX sediment-trap floats (near float 1 or 2). A. Initial activities - timing and sequence of the first two days partially determined by when and where D'Asaro floats surface: 1) Round-One CTD calibration profile and water sampling for each float. CTD profile to be taken as float leaves surface on its down profile. Water sampling for Winkler oxygen, chlorophyll, nutrients, POC/PON, FACScan, FlowCAM, other samples as possible; 2) Lampitt half-day test for ballasting; deploy for short period and retrieve; 3) Checkley SOLOPC deployments; 4) Lampitt APEX deployments, 5) Wesberry APEX deployment. B. Begin Round-One CTD surveys - occupy large and small survey patterns in whatever order is most efficient (see Fig. 1). At a minimum, CTD profiles and water collection at box center and corners; for 100-km box, at least one or two profiles mid-way between corners as time and weather permits (note: objective is to complete 100-km survey in approx. 2 days). C. Opportunistic activities - during or after Round-One or -Two surveys: 1) CTD calibration profile and water sampling for each glider must be done once during the cruise, if it is not possible to do during float calibration profiles. Exact timing is not critical: CTD profile and water sampling for Winkler oxygen, chlorophyll, nutrients, POC, FACScan, FlowCAM, other samples as possible; 2) mid-day optics profiles near floats - ac9, etc., when they surface - floats will surface in daylight ~ every 72 hours (logistics to be there, whenever possible) 3) zooplankton net tows near SOLOPC floats. D. Mid-cruise - timing and sequence partially determined by when and where D'Asaro floats surface: 1) Round-Two CTD calibration profile and water sampling for each float. CTD profile to be taken as float leaves surface on its down profile. Water sampling for Winkler oxygen, chlorophyll, nutrients, POC/PON, FACScan, FlowCAM, other samples as possible; 2) Retrieve Lampitt floats at end of five-day cycle. 3) Redeploy Lampitt floats at convenient time in this cycle. E. Begin Round-Two CTD surveys - occupy large and small survey patterns in whatever order is most efficient. At a minimum, CTD profiles and water collection at box center and corners; for 100-km box, at least one or two profiles mid-way between corners as time and weather permits (objective is to complete 100-km survey in approx. 2 days). F. End-cruise - timing and sequence partially determined by when and where D'Asaro floats surface: 1) Round-Three CTD calibration profile and water sampling for each float. CTD profile to be taken as float leaves surface on its down profile. Water sampling for Winkler oxygen, chlorophyll, nutrients, POC/PON, FACScan, FlowCAM, other samples as possible; 2) Retrieve Checkley floats; 3) Retrieve Lampitt floats; 4) depart for 20 May arrival in Reykjavik.

The three boxes will be occupied twice during the cruise. CTD profiles and water sampling at corners and centers of the boxes; additional sampling on the 100-km box as time and weather permits.
