CORAL REEF MONITORING

 

MONITORING

Understanding the exposure of the nation’s living marine resources such as shellfish and corals to changing ocean chemistry is a primary goal for the NOAA OAP. Repeat hydrographic surveys, ship-based surface observations, and time series stations (mooring and ship-based) in the Atlantic, Pacific, and Indian Oceans have allowed us to begin to understand the long-term changes in carbonate chemistry in response to ocean acidification.


Buoys & Moorings

There are currently 19 OAP-supported buoys in coastal, open-ocean and coral reef waters which contribute to NOAA's Ocean Acidification Monitoring Program, with other deployments planned.

Currently, there are two types of floating devices which instruments can be added in order to measure various ocean characteristics - buoys and wave gliders. Buoys are moored, allowing them to remain stationary and for scientists to get measurements from the same place over time. The time series created from these measurements are key to understanding how ocean chemistry is changing over time. There are also buoys moored in the open-ocean and near coral reef ecosystems to monitor the changes in the carbonate chemistry in these ecosystems. The MAP CO2 sensors on these buoys measure pCO2 every three hours.

Ship surveys

Research cruises are a way to collect information about a certain ecosystem or area of interest.

For decades, scientists have learned about physical, chemical and biological properties of the ocean and coasts by observations made at sea. Measurements taken during research cruises can be used to validate data taken by autonomous instruments. One instrument often used on research cruises is a conductivity, temperature, and depth sensor (CTD), which measures the physical state of the water (temperature, salinity, and depth). The sensor often goes in the water on a rosette, which also carries niskin bottles used to collect water samples from various depths in the water column. Numerous chemical and biological properties can be measured from water collected in niskin bottles.


Ships of Opportunity

Ships of Opportunity (SOPs) or Volunteer Observing Ships (VOSs) are vessels at sea for other reasons than ocean acidification studies, such as commercial cargo ships or ferries.

The owners of these vessels allow scientific instrumentation that measures ocean acidification (OA) parameters to be installed and collect data while the ship is underway. This allows data on ocean chemistry to be collected in many remote areas of the world's ocean, such as high latitude waters, long distances from land (e.g. mid-basin waters), and places not easily accessible by research cruises. These partnerships have greatly increased the spatial coverage of OA monitoring world-wide. To learn more, check out the Ships of Opportunity programs established by the NOAA Pacific Marine Environmental Laboratory (PMEL) and the NOAA Atlantic Oceanographic Marine Laboratory (AOML).


Wave Gliders

Scientists at the NOAA Pacific Marine Environmental Laboratory (PMEL) are working with engineers at Liquid Robotics, Inc. to optimize a Carbon Wave Glider.

This instrument (pictured above) can be driven via satellite from land. Carbon Wave Gliders can be outfitted with pCO2, pH, oxygen, temperature and salinity sensors, and the glider’s equipment takes measurements as it moves through the water. The glider’s motion is driven by wave energy, and its sensors are powered through solar cells and batteries, when needed.


CORAL REEF MONITORING

NOAA’s Coral Reef Conservation Program (CRCP) in partnership with OAP is engaged in a coordinated and targeted series of field observations, moorings and ecological monitoring efforts in coral reef ecosystems.

These efforts are designed to document the dynamics of ocean acidification (OA) in coral reef systems and track the status and trends in ecosystem response. This effort serves as a subset of a broader CRCP initiative referred to as the National Coral Reef Monitoring Plan, which was established to support conservation of the Nation’s coral reef ecosystems. The OAP contributes to this plan through overseeing and coordinating carbonate chemistry monitoring. This monitoring includes a broadly distributed spatial water sampling campaign complemented by a more limited set of moored instruments deployed at a small subset of representative sites in both the Atlantic/Caribbean and Pacific regions. Coral reef carbonate chemistry monitoring is implemented by researchers at the NOAA Atlantic Oceanographic & Meteorological Laboratory (AOML) and NOAA's PIFSC Coral Reef Ecosystems Division.

Assessing Vulnerability to a Changing Ocean: Investigating impact and option for adaptation

Assessing Vulnerability to a Changing Ocean: Investigating impact and option for adaptation

NOAA Ocean Acidification Program

In certain areas of the US, marine resources and the communities that depend on them are particularly vulnerable to the impacts of ocean and coastal acidification along with other ocean changes. The NOAA Ocean Acidification Program recently awarded funding for three regional vulnerability assessment projects in the Chesapeake Bay, Northeast US and US West Coast. The projects bring together oceanographic, fisheries and aquaculture data and social science to assess vulnerability of dependent communities and industries, anticipate challenges they may face, and explore adaptations options.

Assessing vulnerability of the Atlantic Sea Scallop social-ecological system in the northeast waters of the US

Samantha Seidlecki (University of Connecticut), Lisa Colburn (NOAA Northeast Fisheries Science Center), Shannon Meseck (NOAA Northeast Fisheries Science Center)

Of the fisheries made up of calcifiers in the Northeast United States, the Atlantic sea scallop fishery is worth more than $500 million per year, is the second highest fisheries revenue in the United States, and the largest wild scallop fishery in the world. The vulnerability and resilience of fishing communities to the effects of warming and Ocean Acidification (OA) on Northeast species is dependent on their adaptive capacity in relation to both social and environmental exposure and sensitivity factors. Communities that harvest a diversity of species may adapt more easily than communities that specialize in one or a few species. The regional contribution of sea scallop to total regional landed value has steadily increased over recent decades as has fishing community dependence on it as a source of revenue. Prior work projecting impacts to scallops in the region found that sea scallop biomass may decline by more than 50% by the end of the century with a large impact on the fishery (Cooley et al. 2015; Rheuban et al. 2018), but new tools and lab results are available for this proposed work that may alter this assessment. The team is working the hypothesis that a spatially- explicit regional projection of changes relative to sea scallop fishing zones can inform fishery management and allow communities that rely on Atlantic sea scallops to plan and become more resilient to future change. This work will develop a recommendation to management to assist scallop industry stakeholders and managers with changes in the fishery that result from projected OA and temperature changes.

Ocean acidification could have deep impacts for salmon in the Puget Sound. 

Tiffany Grunzel from the University of Washington Communications Leadership program, interviews Dr. Shallin Busch (NOAA), Dr. Chase Williams (UW), and Robert Purser Jr. (Susquamish Fisheries) about the direct and indirect impacts of ocean acidification on salmon and what this could mean for tribal culture and the seafood industry.

Mukilteo scientist tries to discover why C02 is hurting oceans

HeraldNet

Shallin Busch is a Mukilteo-based ecologist whose research is linking ocean acidification to the deteriorating health of the Puget Sound ecosystem. The Mukilteo team has looked at or is looking at ocean acidification effects on krill, salmon, Dungeness crab, black cod and pteropod (marine snails). So far it has found that lower pH levels lead to lower survival and slower development rates, as well as changes in behavior.
