6.6.3 Project description
The role of AEON’s passive acoustic monitoring is to provide long-term observations of human and biological activity as well as changes in environmental conditions in support of all four AEON Objectives. The network provides simultaneous, long-term monitoring of soundscapes and multiple acoustically relevant parameters such as marine mammal behavior and prey concentration at key locations where the effects of changes in the Labrador and Gulf Stream currents are projected to impact the Gulf of Maine. At each network site, AEON employs the latest generation of JASCO’s AMAR recorder mounted on an Autonomous Long-Term Observatory (ALTO) lander with ancillary sensors. In addition to the lander recovery and re-deploy, on each deployment effort the team collects CTD profiles to characterize hydrographic conditions at the sites, conducts net sampling to collect biological specimens at each site, and conducts fine-scale (roughly 5n.mi by 5 n.mi) multi-frequency acoustic surveys at each site

Plankton nets, pulled through the water down to 650 feet, collect small marine animals such as fish larvae, crab larvae, copepods, and small jellyfish. Special equipment collects information on nutrients, acidity, temperature, salinity, and other parts of the marine environment. Dedicated observers count and photograph marine mammals, turtles, and seabirds seen along the cruise tracks to better understand their migrations and how they find food and habitat on their journeys. EcoMon surveys are conducted at 120 randomly selected stations and 35 fixed stations throughout the continental shelf and slope of the northeastern U.S., from Cape Hatteras, N.C., to Cape Sable, Nova Scotia, and cover all of Georges Bank and the Gulf of Maine. Precursor surveys to EcoMon include: - Marine Resources Monitoring, Assessment, and Prediction program (MARMAP; 1977– 1987) - Herring – Sandlance (1988–1994) - Georges Bank Global Ocean Ecosystems Dynamics (GLOBEC; 1995–1999) Data are stored at NCEI and are publicly accessible: https://www.ncei.noaa.gov/access/metadata/landing-page/bin/iso?id=gov.noaa.nodc:0187513

6.9.3 Project description
A new agreement between NOAA’s Northeast Fisheries Science Center, the Marine Biological Association in Plymouth, England and the Woods Hole Oceanographic Institution will allow a plankton survey to resume. The survey was originally conducted across the Gulf of Maine from 1961 to 2017. The survey uses a continuous plankton recorder (CPR), a sampling device that is about 1 meter (roughly 3 feet) long. In this survey, it is towed from so-called “ships of opportunity,” such as merchant vessels. These vessels ply the same routes between ports from year to year. Scientists refer to the routes as survey transects. The recorder stays at a depth of about 10 meters (roughly 33 feet). It filters and collects plankton from the water over long distances. The plankton samples are stored on silk mesh in a cartridge inside the instrument and are analyzed later in a laboratory. “The value of sampling in an area accumulates each subsequent year, building a dataset of evidence and insight that we can use to understand recent changes in the marine ecosystem of the Gulf of Maine,” said David Johns, head of the CPR Survey at the Marine Biological Association. “We can compare our new dataset with the historical time series, and start to put these changes into context in a warming world.” Data can be found here: https://obis.org/dataset/9ad0f8eb-b983-418d-b881-3b672d9e0005

6.10.3 Project description
This MBON project will address a crucial gap for understanding phenological and long-term change in the Gulf of Maine marine ecosystem that has been identified by the Integrated Sentinel Monitoring Network (ISMN) - namely, time series observations of plankton biodiversity at subannual scales. Time series collections will be conducted at a station located in Wilkinson Basin in western Gulf of Maine and a station located in the Maine Coastal Current. NERACOOS and NROC, and the ISMN will undertake responsibility for finding sustained support of these time series, which were established over a decade ago. Phytoplankton and micro and mesozooplankton abundance and species diversity will be microscopically enumerated, and water samples for processing with an Imaging FlowCytobot and eDNA will be collected and analyzed. The ISMN will incorporate a citizen-science initiative to document jellyfish abundance. The observations thus compare traditional with new approaches to biodiversity assessment, expanding MBON into a coastal ecosystem where change is occurring rapidly.

6.11.3 Project description
The Gulf of Maine (GoM) is a highly productive shelf sea that constitutes a large part of the N.E. US Continental Shelf. We have run a time series across the GoM for the last 8 years known as GNATS (Gulf of Maine North Atlantic Time Series). It consists of monthly, cross-Gulf sampling on ships of opportunity, during clear-sky days, so that we are assured concurrent measurements from ship and satellite (ocean color, SST). The power of this strategy is seen in our 95% success rate for being at sea during clear, high quality overpasses (randomly, one would expect a success rate of ~10% due to the GoM cloud climatology). We then can extrapolate our large shipboard data set of carbon cycle parameters to regional scales using synoptic remote sensing. GNATS includes a suite of carbon-specific standing stocks and rate measurements (e.g. POC, PIC [calcite], DOC, primary productivity, and calcification) plus hydrographic, chemical and optical measurements. Through coordinated ship/satellite measurements, we can constrain the major carbon production terms of the Gulf, follow their monthly variation using synoptic remote sensing, and regionally tune satellite algorithms. GNATS documents not only marine carbon pools, but it includes carbon supplied from the terrestrial watershed; this is why the Gulf is optically-dominated by Case II waters. We propose to A) continue GNATS, coordinated ship and satellite measurements for another 3 years, B) provide monthly, regional estimates of the standing stock and production terms for the various particulate and dissolved carbon fractions based on satellite ocean color observations and C) perform a statistical comparison of photoadaptive parameters in the Mid-Atlantic Bight and GoM to examine how broadly we can extrapolate these results along the NE U.S. Continental Shelf. Deliverables of this work will be: ship-based quantification of the various components of the carbon cycle in the GoM (standing stocks of POC, PIC, DOC plus primary production/calcification rates), an improved DOC algorithm, tuning of satellite carbon algorithms for the NE Continental Shelf, and documentation of the long- term biogeochemical and ecological changes occurring in the GoM carbon cycle. Quantification of the variability in the composition and concentration of dissolved and particulate carbon over a wide range of temporal and spatial scales is the first step towards understanding the role of coastal ecosystems in the global carbon cycle.

Researchers at NOAA Fisheries Northeast Fisheries Science Center monitor the waters of the Gulf of Maine using passive acoustic recorders that collect ambient sound data. These data are used to characterize soundscapes and detect the presence of species of interest, such as marine mammals, fish, and invertebrates. The current mooring designs include hydrophones to record ambient sound and VR2AR acoustic releases. No animals are currently being tagged within these monitoring efforts. Thus, all detections are of opportunity and hopefully will contribute valuable information to other researchers. Tagged protected fish will be detected on the receivers.

6.21.3 Project description
Annual Alexandrium catenella blooms in the Gulf of Maine produce potent neurotoxins that accumulate in shellfish and cause Paralytic Shellfish Poisoning (PSP) in human consumers. As part of its lifecycle, A. catenella form cysts, which are dormant cells that settle into the sediment and can later germinate, triggering harmful algal blooms. These blooms are monitored through an annual research cruise that collects data on cyst abundance. Figure 1 below shows the abundance of cysts in the top 1-cm sediment layer collected in October 2023 (cells/cm²).This dataset includes coastal station sites pulled from Figure 1, where Alexandrium catenella cyst samples were collected to track cyst abundance. In addition, it features model-simulated surface time series data for A. catenella, providing insight into bloom patterns and dynamics.Disclaimer: This result is for experimental use only. This data is currently being used for a Gulf of Maine Alexandrium catenella predictive model animation product only available on our developers website.
