The Gulf of Maine, a semienclosed basin on the continental shelf northwest Atlantic Ocean, is fed by surface and deep water flows from outside gulf: Scotian Shelf Water (SSW) Nova that enters gulf at slope depth along bottom through Northeast Channel. There are two distinct types water, Labrador Slope (LSW) Warm (WSW); it these masses major source dissolved inorganic nutrients to gulf. It has been known for some time volume inflow waters either type Maine variable, covaries with magnitude...

Cold surface temperatures, reflecting Scotian Shelf origins and local tidal mixing, serve as a tracer of the Eastern Maine Coastal Current its offshore extensions, which appear episodically cold plumes erupting from eastern shelf. A water plume emanating in May 1994 was investigated using advanced very high resolution radiometer (AVHRR) imagery, shipboard surveys physical biochemical properties, satellite‐tracked drifters. Evidence is presented that suggests some waters were entrained within...
Abstract We used a coupled biophysical model to investigate larval transport and connectivity patterns in the Gulf of Maine lobster ( Homarus americanus ) population. Biological ‘particles’ were released at over 21 000 locations every 10 days 4‐month hatching period, followed from through late postlarval stage. In addition circulation dispersion, calculations included spatial egg production, temporal hatching, temperature‐dependent development, vertical distribution mortality. ran for three...
Successful area-based ocean management relies on long-term, persistent biological monitoring using reliable observation assets. Underwater electric gliders fill a unique niche compared to other platforms because they can autonomously survey across diverse environments—from shallow coastal waters remote offshore areas—for weeks months at time. Gliders equipped with passive acoustic (PAM) devices are capable of robust, continuous near-real-time numerous species whales. Here, we highlight five...
Abstract The US offshore wind industry is maturing with several projects in various stages of development. These require site and environmental data before during operation. Conventional techniques such as fixed‐bottom meteorological towers present economical permitting challenges for the US. Floating Light Detection Ranging (LiDAR) buoys offer significant advantages including reduced costs, less permitting, reusability. This paper presents validation first floating LiDAR buoy Northeast...

The Nantucket Shoals Flux Experiment (NSFE) was a collaborative effort to measure the alongshelf transport of mass, heat, salt and nutrients from March 1979 through April 1980 with dense army consisting moored current, temperature bottom pressure instruments in an across-shelf upper-slope transect south Island. component that experiment is described here. Bottom recorders were deployed at stations N1 (46 m), N2 (66 N4 (105 N5 (196 m) during two half-year periods. spring–summer (SUMMER)...

Traditional means of observing the ocean, like fixed mooring stations and radar systems, are difficult expensive to deploy provide coarse-grained data measurements currents waves. In this paper, we explore use inexpensive wireless drifters as an alternative flexible infrastructure for fine-grained ocean monitoring.
