Cape Shirreff Situation Reports 2023-2024

These reports highlight science activities and events from the U.S. Antarctic Marine Living Resources Program Field Camp at Cape Shirreff, Livingston Island, part of the South Shetland Islands of Antarctica

First Demographic Parameter Estimates for the Mediterranean Monk Seal Population at Madeira, Portugal

We provide the first comprehensive demographic assessment of the Endangered Mediterranean monk seal Monachus monachus population residing in the Madeira Archipelago to identify factors that may impede population growth.

Terrestrial Pathogen Pollutant, Toxoplasma gondii, Threatens Hawaiian Monk Seals (Neomonachus schauinslandi) Following Heavy Runoff Events Journal of Wildlife Diseases

To understand environmental factors influencing Hawaiian monk seal exposure to Toxoplasma gondii, we examined monk seal strandings from toxoplasmosis in relationship to location and rainfall patterns throughout the main Hawaiian Islands.

Passive Acoustic Research in the Atlantic Ocean

We use innovative passive acoustic technologies to study the behavior, movements and distribution of marine animals and their contribution to soundscape ecology. We also evaluate how man-made sounds affect marine animals.
This illustration shows the variety of technologies that NOAA Fisheries researchers use to record underwater sounds and study marine animals. The seascape shows bottom- mounted and drifting acoustic recorders, underwater autonomous vehicles, Atlantic cod and humpback whale with tags, and instruments deployed from a NOAA ship and small boat. Colored circles show a zoomed-in view of the instruments and indicate the type of data collected: green for real-time data, orange for archival data, and blue for active NOAA Fisheries studies marine animals by using a variety of technologies to record underwater sounds, including archival passive acoustic recordings (orange), real-time acoustic data collection (green), and active acoustics (blue).

Protected Species Gear Research

We work closely with the commercial fishing industry to reduce harmful interactions with marine mammals, turtles, and other protected species.

Developing Viable On-Demand Gear Systems

On-demand gear development continues to evolve with the help of industry.

Borrow From The Northeast Fisheries Science Center Gear Library

The gear library is a collection of on-demand or “ropeless” systems, built with help and donations from environmental and academic organizations, that we lend to fishermen for testing.

Atlantic Marine Assessment Program for Protected Species

We conduct surveys and develop abundance and distribution models to better understand how protected species such as whales, dolphins, and sea turtles use our waters.

Age-Specific Survival and Reproductive Rates of Mediterranean Monk Seals at the Cabo Blanco Peninsula, West Africa

Live encounter data provides the first complete set of survival rate estimates for the Endangered Mediterranean monk seal birth into adulthood, as well as the first age-specific reproductive rates for the species.
