Hollow Core Fiber Methane Sensor

Anna Michel & Jason Kapit
We have developed a hollow core fiber optic sensor capable of measuring dissolved methane gas in liquids using only nanoliters of sample gas. The sensor is based on an anti-resonant hollow core fiber combined with a permeable capillary membrane inlet which extracts gas from the liquid for analysis.

Southern Cape Cod Bay hypoxia data

Malcolm E. Scully, Tracy L. Pugh, W. Rockwell Geyer, Amy Costa & Owen C. Nichols
This project investigated the distribution of low dissolved oxygen bottom waters (hypoxia) in southern Cape Cod Bay. Hypoxia was documented for the first time in late summer 2019 and 2020 despite extensive monitoring for the past decade. The data include: 1) measurements of bottom dissolved oxygen collected in 2019 by the Massachusetts Division of Marine Fisheries (MDMF) and the Center for Coastal Studies (CCS) ; 2) full water column profiles of temperature, salinity, chlorophyll fluorescence,...

Revisiting HF ground wave propagation losses over the ocean: a comparison of long-term observations and models

Anthony Kirincich & Eve Cinquino
This data was collected by Kirincich as part of the NSF-sponsored High Frequency Radar Winds program, with the goal of understanding the errors in present day HFR-based wind extraction algorithms that are due to variations in the signal losses along the transmission path. Understanding variations in the received power levels for land-based high frequency radar systems is critical to advancing radar-based estimates of winds and waves. We use a long-term record of one-way high frequency...

Data from the 2018 dye release cruise south of Martha’s Vineyard, MA

Irina Rypina, Anthony Kirincich & Thomas Peacock
On Aug 16-17, 2018 a rhodamine dye experiment was conducted in the coastal ocean south of Martha’s Vineyard, MA. One of the experiment’s aims was to investigate the exchanges, or the absence of such, between the mixed layer and the ocean underneath over a time scale of about a day.

Investigating thermal physiology in large whales via aerial infrared thermography

Gina Lonati, Daniel Zitterbart, Carolyn A. Miller, Peter Corkeron, Christin Murphy & Michael J. Moore
The critically endangered status of North Atlantic right whales (NARWs, Eubalaena glacialis) warrants the development of new, less invasive technology to monitor the health of individuals. Combined with advancements in remotely piloted aircraft systems (RPAS, commonly “drones”), infrared thermography (IRT) is being increasingly used to detect and count marine mammals and study their physiology. We conducted RPAS-based IRT over NARWs in Cape Cod Bay, Massachusetts, USA in 2017 and 2018. Observations demonstrated three particularly useful...

Long-Term evolution of non-transform discontinuities at the Mid-Atlantic Ridge, 24°N - 27°30′N

Reducing effort in the U.S. American lobster (Homarus americanus) fishery to prevent North Atlantic right whale (Eubalaena glacialis) entanglements may support higher profits and long-term sustainability

Hannah Myers & Michael J. Moore
Supplemental data for Reducing effort in the U.S. American lobster (Homarus americanus) fishery to prevent North Atlantic right whale (Eubalaena glacialis) entanglements may support higher profits and long-term sustainability. Figure 5: Estimated North Atlantic right whale population, number of calves, observed mortalities and serious injuries, and diagnosed cause of death or serious injury. Diagnosed entanglements have increased significantly since the population has been in decline. Data from Waring et al. 1997, Kraus et al. 2001,...

Observations of turbulence and the geometry and circulation of windrows in a small bay in the St. Lawrence Estuary.

Seth Zippel, Ted Maksym, Malcolm E. Scully, Peter Sutherland & Dany Dumont
Measurements of ocean turbulence, waves, and the geometry and circulation of windrows were made over 5 days in early March in a small bay in the St. Lawrence Estuary. Measurements were made from a small zodiac and from a SWIFT drifter. Two acoustic doppler velocity profilers (ADCPs) were used from the zodiac to measure water velocity and turbulent kinetic energy (TKE) dissipation rates near the surface. The acoustic backscatter from the ADCPs was used in...

Sentry Underway Data for Cruise AT42-03, Sentry Dives 500-509

This package is the complete data package prepared by the Sentry team while at sea. Some parts of the data package will be available in other locations. We will update the metadata to include references to these data as they are available. This package contains data from Sentry Dives 500-509. These dives were done as part of AT42-03, aboard the R/V Atlantis in 2018. More information about AT42-03 is available from the Rolling Deck to...

Tidal dispersion in short estuaries

Adrian Mikhail P. Garcia & W. Rockwell Geyer
The salinity distribution of an estuary depends on the balance between the river outflow, which is seaward, and a dispersive salt flux, which is landward. The dispersive salt flux at a fixed cross-section can be divided into shear dispersion, which is caused by spatial correlations of the cross-sectionally varying velocity and salinity, and the tidal oscillatory salt flux, which results from the tidal correlation between the cross-section averaged, tidally varying components of velocity and salinity....

Discovering hydrothermalism from afar: in situ methane instrumentation and change-point detection for decision-making

Anna Michel, Scott Wankel, Victoria Preston, Genevieve E. Flaspohler, Jason Kapit, William A. Pardis, Sarah Youngs, Donald E. Martocello, Peter Girguis & Roy, Nicholas Roy, Nicholas
Seafloor hydrothermalism plays a critical role in fundamental interactions between geochemical and biological processes in the deep ocean. A significant number of hydrothermal vents are hypothesized to exist, but many of these remain undiscovered due in part to the difficulty of detecting hydrothermalism using standard sensors on rosettes towed in the water column or robotic platforms performing surveys. Here, we use in situ methane sensors to complement standard sensing technology for hydrothermalism discovery and compare...
