attribute	NC_GLOBAL	summary	String	Near-real-time subsurface sea water temperature and pressure measured by autonomous temperature-depth loggers (ZebraTech Moana TD) attached to the fishing gear of commercial vessels taking part in the Maine Coast Fishermen's Association (MCFA) programme, in the Gulf of Maine. Gears: trawls and gillnets. Each trajectory (tow_id) is one gear deployment: a down-profile while the gear is set, a bottom or fishing phase, and an up-profile when it is hauled (segment_type). Data are offloaded to a deck unit when the gear returns on board and published within hours. Every sample is kept: the automated FVON quality-control tests only flag data (qc_* variables, scale 0 not evaluated, 1 good, 3 suspect, 4 bad, 9 missing value); nothing is removed or adjusted. Vessels are anonymised.

attribute	qc_gear_type	comment	String	One verdict per tow, computed on the RAW GPS fixes of the deck unit. Two gear classes exist: mobile (trawls, seines) and fixed; longlines, set longlines, gillnets, traps and pots are all processed as fixed gear. No sample of the tow has a position, or first and last fix both missing: bad (4). Fixed gear whose first and last real GPS fixes are further apart than 10 x the maximum pressure (in metres): suspect (3); fixed gear with fewer than two fixes: not evaluated (0). Mobile gear with only one of the first/last fix missing: suspect (3). Mobile gear starting and ending less than 200 m apart while averaging more than 10 km/h along the track, or with zero duration: suspect (3). Seines and handlines: straight-line speed between first and last fix above 10 km/h, or zero duration: suspect (3). Where an operator has corrected a tow position afterwards (for example gear set or hauled by another vessel), the published position is the corrected one and this flag still records that the raw fixes were suspect.

attribute	qc_mud	comment	String	Fixed gear only; mobile gear and tows without segments are always good (1). Detects sediment packed around the thermistor, which slows its response from about 1 s to minutes: the up-profile stays biased toward the bottom temperature. Needs at least 2 degree_C surface-to-bottom contrast, casts long enough to resolve the lag, a mid-column up-minus-down difference toward the bottom temperature, and a lag signature on the ascent (full lag, wash-out, pinned, or pinned then released). A profile that is offset but keeps its shape is treated as a water-mass change. The down-profile is flagged only with seabed evidence. Every detection is bad (4), whether automatic or confirmed by an operator; this test never reports suspect (3).
