The Dataset's Variables and Attributes

Row Type Variable Name Attribute Name Data Type Value
attribute NC_GLOBAL access_formats String .htmlTable,.csv,.json,.mat,.nc,.tsv,.esriCsv,.geoJson
attribute NC_GLOBAL acquisition_description String CTD casts at discrete stations located along transects.\u00a0 Most transects
are oriented either across-shelf or along-shelf (one is a mixture).\u00a0
Sampling was limited to 2 hrs. in the middle of the tidal cycle, on either
flood or ebb tides.\u00a0 CTD was a YSI Castaway:
[www.sontek.com/productsdetail.php?CastAway-
CTD-11.\u00a0](\\"http://www.sontek.com/productsdetail.php?CastAway-
CTD-11.\\u00a0\\") Calibration dates and additional information are supplied
in the headers of each data file.\u00a0 Headers also contain coordinates of
the instrument at the start and stop of each cast.

Frenchman Bay is a long transect that had to broken into two with half run on
each cruise, in order to stay within our 2 hour tidal phase window.\u00a0
Hence the renchman Bay cruises have an \"Upper\" vs. \"Lower\" designation,
but the station coordinates are continuous.\u00a0 To accommodate weather
conditions and/or logistical delays, we did not consistently run the same set
of stations on each cruise designated \"Upper\" vs. \"Lower\" cruise, but the
designation indicates the general location of stations.

attribute NC_GLOBAL instruments_0_description String The Conductivity, Temperature, Depth (CTD) unit is an integrated instrument package designed to measure the conductivity, temperature, and pressure (depth) of the water column. The instrument is lowered via cable through the water column and permits scientists observe the physical properties in real time via a conducting cable connecting the CTD to a deck unit and computer on the ship. The CTD is often configured with additional optional sensors including fluorometers, transmissometers and/or radiometers. It is often combined with a Rosette of water sampling bottles (e.g. Niskin, GO-FLO) for collecting discrete water samples during the cast. This instrument designation is used when specific make and model are not known.

Extracted from the NSF award abstract:
Existing larval transport models focus mainly on along-shelf transport and have done little to explicitly incorporate the effects of cross-shelf mixing and transport processes. Yet cross-shelf transits (both outgoing and incoming legs) are critical components of the dispersal paths of coastal invertebrates. This project will explore the role of cross-shelf mixing in the connectivity of blue mussel populations in eastern Maine. Previous work has shown that the Eastern Maine Coastal Current (EMCC) begins to diverge from shore southwest of the Grand Manan Channel and creates a gradient in cross-shelf mixing and larval transport, with cross-shelf mixing being more common on the northeastern end, episodic in the transitional middle area, and then becoming rare in the southwestern half of the region of the Gulf of Maine. As a result, the investigators predict that northeastern populations of mussels are seeded mostly from up-stream sources, while a significant component of self-seeding (local retention) exists in southwestern populations. Larvae settling in the intervening bays are expected to be derived from a mixture of local and up-stream sources. Using a combined empirical and theoretical approach hydrographic, current profile, and larval vertical migration data will be collected and used to develop and validate a high-resolution coastal circulation model coupled to a model of larval behavior. The investigators will model simulations in different years using the empirical data from mussel reproductive output and spawning times. Connectivity predicted from this model will be then tested against independent empirical estimates of connectivity based on trace element fingerprinting for larvae which can be connected to specific natal habitats. Regions of agreement and discrepancy in the model will be identified to guide additional data collection and model refinement. This iterative process will ensure an understanding of both larval transport patterns and processes, and provide estimates of inter-annual variability in connectivity for blue mussel populations in the Gulf of Maine.
