Scientists and R/V Pelican crew members recover the second of two sediment traps from a depth of 600 meters from the sea surface.

A Collaborative Effort Investigates the Biological Carbon Pump, Deploying Sediment Traps Hundreds of Meters Below

A team of scientists from AOML, the U.S. Geological Survey (USGS), and the University of South Carolina retrieve a sediment trap from the Gulf of Mexico, spending months processing and examining the flurry of microscopic shells and environmental DNA (eDNA) of biological debris collected by the trap, known as “marine snow.” This collaborative NOAA–USGS research project uses these sediment trap samples to investigate the biological carbon pump, the ocean’s role in removing atmospheric carbon, and climate change patterns.

On a beautiful calm day, the SeaTrac, a thin yellow vessel roughly the shape of a stand up paddleboard, glides aong the glassy waters of the Great Lakes, easily navigating the shallows with trees and jetties of rocks beyond it and a sea bordering the skies somewhere that we can barely define.

Failing Upwards: Developing an Autonomous Surface Vehicle to Advance ‘Omics Research 

For engineers and scientists, sometimes failure means progress. When developing a new technology, the process is to field test, fail, tweak, and test again, each time failing a little less and learning what does and does not work until – finally – they get it right. On August 5, 2023, scientists from NOAA’s Great Lakes […]

AOML Interns Dive into DNA Extraction and Processing Coral Samples for ‘Omics Analyses 

Only a few weeks into summer, Coral Program Interns Lorelei Ing, Taylor Gill, Zachary Zagon and Kenzie Cooke have been hard at work as they process coral samples and perform DNA extractions in preparation for ‘Omics analyses that will help to better understand how the genetic structure of corals influences their resilience to environmental stressors. The Coral Program falls within the Ocean Chemistry and Ecosystems Division (OCED) at NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML).

New study highlights major step forward in monitoring ocean health

In a major step forward for monitoring the biodiversity of marine systems, a new study published in Environmental DNA details how Monterey Bay Aquarium Research Institute (MBARI) and NOAA’s Atlantic Oceanographic & Meteorological Laboratory (AOML) researchers are using autonomous underwater robots to sample environmental DNA (eDNA). eDNA allows scientists to detect the presence of aquatic species from the tiny bits of genetic material they leave behind. This DNA soup offers clues about biodiversity changes in sensitive areas, the presence of rare or endangered species, and the spread of invasive species—all critical to understanding, promoting, and maintaining a healthy ocean.

How the Ocean’s Tiniest Creatures Respond to Changes in the Marine Environment, Revealed by Machine Learning Analysis of ‘Omics Data

Although too tiny to be seen by the naked eye, microscopic organisms have a big impact on our planet – supporting fisheries, degrading pollutants, and helping regulate the earth’s climate. A new study published in Nature Communications employed cutting edge research techniques (collectively referred to as ‘omics) to reveal how the ocean’s tiniest creatures respond to changes in the marine environment. This work addressed a number of objectives in the NOAA ‘Omics Strategic Plan, which calls for the characterization of food webs that sustain fisheries and vulnerable species.

Exploring Environmental DNA

Have you ever wondered what animals might be present in a particular habitat or traveled through a certain area of the ocean? Scientists are able to use environmental DNA or “eDNA” sampling to help answer those questions. NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) has recently released a new educational video series, “Exploring Environmental DNA” on their website and Youtube channel.

The Spirit of International Cooperation Drives Oceanographic Discovery Aboard Tara

At 20:00 at 64°S in the austral summer month of February, the sun was still high in the sky. It cast a delicate light over the sea surface dotted with icebergs, which ranged from small misshapen chunks to massive angular structures with marbled cliffsides. In January and February 2022, I took part in an Antarctic voyage aboard the French schooner Tara. My participation was part of a partnership between NOAA and AtlantECO, a European-led consortium to characterize, quantify, and model Atlantic Ocean ecosystems.

Environmental DNA Sampling Gets an Upgrade and Transitions to New Open-Source Technology

Scientists at NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML),the Cooperative Institute for Marine and Atmospheric Studies (CIMAS) at the University of Miami Rosenstiel School of Marine and Atmospheric Science, and the Northern Gulf Institute at Mississippi State University have engineered a new instrument that will provide valuable information about the biodiversity of aquatic ecosystems. A recently published paper in Hardware X describes the design and creation of a low-cost, open-source sub-surface automated environmental DNA (eDNA) sampler (SASe), for sampling eDNA in the water column. The SASe represents a milestone for AOML as one of the first pieces of technology to go through a rigorous transition process from the desks of scientists in the laboratory, through organizational approval channels, to the wider scientific community with full accessibility to the public.
