Seasonal trends and diel patterns of downsweep and SEP calls in Chilean blue whales (Balaenoptera musculus)

Laura Redaelli, Sari Mangia Woods, Rafaela Landea Briones & Laela S. Sayigh
To learn more about occurrence and behavior of a recently discovered population of blue whales, passive acoustic data were collected for 15 consecutive months (January 2012 – April 2013) in the Chiloense ecoregion of southern Chile. Automatic detectors and manual auditing were used to detect blue whale songs (SEP calls) and D calls, which were then analyzed to gain insights into temporal calling patterns. We found a year-round acoustic presence of D calls, with the...

Quantifying pelagic primary production and respiration via automated in-situ incubation system

Solomon Chen & Matthew Long
We developed and validated a novel automated water incubator that measures in-situ rates of photosynthesis and respiration. This dataset includes raw data, Monte-Carlo simulation method, and processed results from field deployments in Summer, 2021. Deployment of the incubator was conducted near Ucantena Island, Massachusetts, USA. The dataset includes timeseries of automated incubation experiments, reporting dissolved oxygen concentration (DO), temperature, and photosynthetically active radiation (PAR). There are four deployments spanning from late august to early October,...

Temporal trends and effects of noise on upsweep calls of Eastern South Pacific southern right whales

Ellen Jacobs, Rafaela Landea & Laela Sayigh
Eastern South Pacific southern right whales (ESPSRW) are a subpopulation of southern right whales (Eubalaena australis) off the coasts of Peru and Chile recognized by the International Union for the Conservation of Nature (IUCN) as critically endangered as a result of heavy whaling efforts in the late 18th to 20th centuries. Most recent population estimates put their numbers around 50 individuals. To test for the efficacy of passive acoustic monitoring of this population, we recorded...

Numerical model simulating the sea ice and ocean conditions in the Amundsen Sea over the period Jan. 1, 2006 to Dec. 31, 2013

Pierre St-Laurent, Eileen E. Hofmann, Robert M. Sherrell, Sharon E. Stammerjohn, Patricia L. Yager, Mathew Biddle & Amber D. York
Numerous coastal polynyas fringe the Antarctic continent and strongly influence the productivity of Antarctic shelf systems. Of the 46 Antarctic coastal polynyas documented in a recent study, the Amundsen Sea Polynya (ASP) stands out as having the highest net primary production per unit area. Incubation experiments suggest that this productivity is partly controlled by the availability of dissolved iron (dFe). As a first step toward understanding the iron supply of the ASP, we introduce four...

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...

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...
