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.

Old Bay with a new spice: a new buoy helps monitor how carbon dioxide is changing the Chesapeake Bay

Old Bay with a new spice: a new buoy helps monitor how carbon dioxide is changing the Chesapeake Bay

NOAA Ocean Acidification Program

A new Ocean Acidification monitoring buoy was deployed on April 5, 2018 in the largest United States estuary, the Chesapeake Bay. This is the first long-term ocean acidification monitoring buoy and it will be deployed at the mouth of the Chesapeake Bay. The buoy will measure carbon parameters in the estuary, which is particularly vulnerable to changes in carbonate chemistry. These changes could impact economically valuable resources for Bay communities, such as oysters. The data from this buoy will supply models with the information needed to recognize potential areas of vulnerability and what future chemical parameters may look like in the bay, while also expanding the National Ocean Acidification Observing Network. It will also help researchers at NOAA PMEL, University of Delaware and University of Maryland differentiate between human-caused and natural variations in carbonate chemistry in the estuary.

Nina Bednarsek Awarded SeaDoc Society Science Prize

Nina Bednarsek Awarded SeaDoc Society Science Prize

NOAA Pacific Marine Environmental Laboratory

Dr. Nina Bednarsek has been awarded the biennial SeaDoc Society's’ Salish Sea Science Prize for her groundbreaking work on the impacts of ocean acidification on pteropods, planktonic marine snails, as well as enhancing policy and regulatory processes along the US West Coast. Dr. Bednarsek was an NRC postdoctoral research fellow with NOAA Pacific Marine Environmental Laboratory (PMEL) from 2012 - 2015 where she worked with the Carbon Program. Dr. Bednarsek’s research with PMEL has found that the highest impacts on pteropods from ocean acidification is observed in the Salish Sea. Her results show that live pteropod shells undergo dissolution at aragonite saturation state values <1, which is commonly found in subsurface Salish Sea waters and along the Washington coast during the upwelling season.

Assess, anticipate, adapt: Vulnerability and Responses to Ocean Acidification

Assess, anticipate, adapt: Vulnerability and Responses to Ocean Acidification

NOAA Ocean Acidification Program

There are areas in the United States where marine resources and the communities and industries that depend on them are particularly vulnerable to the impacts of ocean acidification. In three US regions, our understanding of vulnerability is being advanced by coupling ocean and social science data to equip communities and industries with the information needed to evaluate, anticipate, and adapt to ocean acidification.
