Using Autonomous Vehicles for Ecosystem Assessments

Scientists from NOAA and the Monterey Bay Research Institute (MBARI) are teaming up on June 3-4, 2019 to conduct a complex mission which will integrate acoustic measurements and autonomous sample collection for analysis of environmental DNA (eDNA).  Through these efforts NOAA scientists hope to develop faster and cheaper ecosystem assessment methods, ensure sustainable fisheries and broaden our understanding of life in the oceans.

New NOAA, Partner Buoy in American Samoa Opens Window into a Changing Ocean

NOAA and partners have launched a new buoy in Fagatele Bay within NOAA’s National Marine Sanctuary of American Samoa to measure the amount of carbon dioxide in the waters around a vibrant tropical coral reef ecosystem. “This new monitoring effort in a remote area of the Pacific Ocean will not only advance our understanding of changing ocean chemistry in this valuable and vibrant coral ecosystem but will also help us communicate these changes to diverse stakeholders in the Pacific Islands and across the United States,” said Derek Manzello, coral ecologist with NOAA’s Atlantic Oceanographic and Meteorological Laboratory.

AOML Temperature Sensor to be Deployed at Reef Sites Worldwide

Researchers with AOML’s Ocean Chemistry and Ecosystems Division have entered into a collaborative agreement with Reef Check Foundation to deploy an AOML-designed temperature sensor at coral reef sites around the world. Measuring only six inches in height, the inexpensive, highly-accurate sensors will greatly enhance efforts to more precisely monitor small-scale temperature fluctuations that occur at reefs over time and at various depths.

Scientists Use 3D Printing Technology to Study Water Chemistry at Coral Reefs

AOML researchers have taken an innovative approach to studying the changing carbonate chemistry of seawater at shallow coral reef sites. Using 3D printing technology made possible by the new Advanced Manufacturing and Design Lab at AOML, researchers with the Acidification, Climate, and Coral Reef Ecosystems Team, or ACCRETE, have created a water sampler in-house.

Global Ocean is Absorbing More Carbon from Fossil Fuel Emissions

The new research published by NOAA and international partners in Science finds as carbon dioxide emissions have increased in the atmosphere, the ocean has absorbed a greater volume of emissions. Though the volume of carbon dioxide going into the ocean is increasing, the percentage of emissions — about 31 percent — absorbed by it has remained relatively stable when compared to the first survey of carbon in the global ocean published in 2004.

New Cruise Studies Red Tide Impacts in South Florida

AOML recently led a multi-agency (NOAA/AOML, NOAA/SEFSC, State of Florida Fish and Wildlife Research Institute, Florida Fish and Wildlife Commission, NOAA/NESDIS, University of South Florida, MOTE Marine Laboratory and Aquarium, and University of Miami) research cruise to study the effects of Southwest Florida’s ongoing red tide. To address such a complex problem as red tide, the cruise brought together a diverse team of experts consisting of commercial fishermen, oceanographers, systems ecologist, phytoplankton ecologist, and fish population biologist. This cruise allowed researchers to take a holistic approach to characterize the extent of the red tide and its impacts. The goal of the cruise was to understand why these blooms happen to better inform effective future response measures and hopefully improve Florida’s resilience to these coastal events.

BEACHES Study Promotes Health & Safety for Beachgoers

Few accessible places represent Earth’s natural beauty quite like our beaches, but looks can be deceiving if there is a bacterial outbreak or contamination from offshore activities. Not being able to see these contaminants puts families at risk of exposure if they aren’t properly warned. The BEACHES project (Beach Exposure And Child Health Study), a collaboration between the University of Miami’s College of Engineering and the Cooperative Institute for Marine and Atmospheric Studies and AOML, along with the Universities of Arkansas and Texas, aims to pair child behavioral science with microbiology to address exposure risk of beachgoers.

NOAA Collaborates with Partners to Test Unmanned Underwater Vehicles which Record Harmful Algal Blooms in Lake Erie

In a collaborative effort between NOAA, the Cooperative Institute for Great Lakes Research, and the Monterey Bay Aquarium Research Institute, research merging robotics with biochemistry will give us a detailed, three-dimensional picture of harmful algal blooms in Lake Erie in near real-time and take water samples for genomic analysis. The end goal is a Harmful Algal Bloom forecast to help managers make decisions about environmental health and public safety pertaining to the lake. AOML’s own Dr. Kelly Goodwin is participating in the project to help with instrument and sample recovery.

Cruising for Conservation: Restoring Florida’s Water Quality

 In August 2018, a team of biological oceanographers and ecologists set sail on the R/V Walton Smith to sample the waters of Biscayne Bay & Florida Bay. AOML has conducted regular interdisciplinary observations of south Florida coastal waters since the early 1990’s. We spoke with Chris Keble, the lead scientist for AOML’s South Florida Ecosystem Restoration Research project, to learn more.
