# MSE Science Data Meeting # Tue 26 July 2005 10:00-11:30 Attending: graybeal, hamilton, ussler, mellinger, chavez, gomes, chaffey, raybould, headley barry Power and data budgets SSDS requirements for MSE - Need to order instruments ASAP: SIAM critical path - new instruments and deployment resources should go in MSE budget (Aug 5) for final proposal Barry: Norteks (2) 6000 m 2MHz HR profiler $17.8k incl. embedded pucks (problems in very clear water?) may be settings for different conditions Wetlabs 3 chan BB2F/BB3F/FLNTU BB3F 3 independent channels use HS2s? replace all? use all the same (HS2 cost 2x ECO)? OK to use HS2 on 20m cage, but cleaner to use all the same. (chfr) disadvantages: comparing different instruments, ECOs will have embedded pucks may be worth getting prototype BB3 and putting it on ROV to see how it behaves over large dynamic range price break for flntu? flntu and bb3F optically the same units? NTU, backscatter units are all relative have a conference call w/ Ian (or someone who has used the instruments ideally, we'd have all the same, spare pool can be smaller, many other tasks become simpler number needed 9/12(if no HS2s) Satlantic ISUS: ok to order Anderaa Optrode: - differences between listed instruments? comms interface? housing? - slow response (not as good on CTDs), but sensitivity is good - biofouling issues? pretty good at depth, some sediment film Satlantic shutter: not for surface unit in air all subsurface have shutters OCR3000->Hyper OCR Seabirds: 37SM have analog inputs? no... SBE16 do have analog channels (xmissometer, fluorometers, seapoint OBS) have 2 SBE16s, need complete instr cluster spare for ROV swap need to have complete BIN replacement (should we have 2 BIN replacements) what is diff btw SBE16, SBE16 Plus? Sediment Traps: usu 10-14 cups, depl length need to know time line, when to deploy traps easier to use pt sur 6 traps, 2800 m cable height of traps on deck limits use of W. Flyer Sampling Rates: what can ADCP do at 10 sec bin avging? Data Management: what is snapshot strategy? decimated data? needed to detect events health and status? ability to request high frequency data needed if we can't to really fast samping, then we need event detection does siam manage instrument on board storage? ussler wants to use snapshot data to detect plume and respond with CTD cruise (needs to justify mobilizing flyer) digital pictures (1 MB photo, 1x/day) SSDS: specific data requirements gathering data products, plots web site larger scale, much development as we go first order of business: give people a place to get their data (chfr) camera data...render picture? just provide bits? need to scope work before phase 1 proposal how to manage data snapshots...how is raw data defined for MSE, no requirement to externally present data need list of what processing is needed by who, and who is responsible for processing steps Profilers: both seahorse and mclane will be connected to SIAM 4 hour sample period battery powered Instrument Access: it is possible to log in to mooring and talk directly to instrument low bandwidth, not expensive up to a point (3000 min/mon, $0.17->$0.45) Sediment Trap Data: go out and recover, dump data and put into SSDS
