OR&R Drift Card Studies

Over the years, NOAA’s Office of drift watch   Response and Restoration (OR&R) and other NOAA workplaces have used flow cards–firstly plastic however now skinny, biodegradable pieces of wood, colored with shiny non-poisonous paint–to learn more approximately the route of ocean currents in a specific region. On the cards are instructions asking the finder to document the date and place determined.
Drift cards are frequently released as part of an oil spill reaction exercise or drill. Our intention in releasing the playing cards is to collect statistics approximately the feasible go with the flow of an oil spill. Drift cards also can suggest where other things, along with stricken fishing boats, marine debris, plankton, or maybe sewage, might glide.
Drift card studies have a number of benefits to us. They are inexpensive, allow us to do a small have a look at over a huge variety of environmental conditions and over a fairly long time frame, and deliver us the advantage of volunteer assistants
On some events within the past, we’ve launched waft cards as part of an real spill response. For example, the predecessor to OR&R launched float playing cards all through the reaction to the December 1976 grounding of the M/V Argo Merchant close to Nantucket Island, Mass. Released from Nantucket Shoals, several of those flow playing cards were determined through the years in Ireland and France. Drift playing cards have been additionally released as part of the reaction to the June 1979 Ixtoc 1 oil well blowout inside the Bay of Campache, 600 miles south of Texas within the Gulf of Mexico. These playing cards have been launched between July and August, 1979.
From 2002 to 2004, OR&R scientists carried out an exploratory take a look at to learn greater approximately the route of ocean currents off Oahu, Hawaii. The purpose of the study become twofold: to find a trend in where floating pollution would possibly pass under different environmental conditions, if launched from the south shores of Oahu, and to present us an idea of wherein we must direct our efforts in future studies. About once a month, volunteers from the oil spill cooperative, Clean Islands Council, released a batch of a hundred cards from Barber’s Point, close to Honolulu. We also launched several sets of special playing cards at some stage in Kona wind events. These occasions, with winds from the south and southwest, normally occur numerous times at some stage in the iciness months in Hawaii and have the capacity to hold pollution to the Waikiki and Diamond Head areas.

Safe Sanctuaries (Florida)
In 2005, a float card release became one issue of the pollutants reaction drill, Safe Sanctuaries 2005(link is external) [PDF, 283 KB]. We designed the examine to version floating pollutants within the Florida Keys National Marine Sanctuary, wherein the drill occurred. In this exercising, OR&R and its co-lead, the National Marine Sanctuary Program, worked carefully with partners in NOAA, the U.S. Coast Guard, and Florida State Department of Environmental Protection to exercising their emergency response talents and to provide education. (You can examine greater about this occasion in the video, Safe Sanctuaries 2005: Emergency Response Drill. Drift playing cards are discussed at approximately 10:30.)

Safe Seas (California)

During the Safe Seas exercise, green waft playing cards had been scattered on beaches at sunrise to symbolize oil and marine particles washed ashore after the hypothetical collision. Shoreline Cleanup Assessment Technique (SCAT) teams that visited the beaches later in the day used the cards to map the region and circumstance of the “oil” and advocate cleanup strategies. (USGS)

The following year in the course of the Safe Seas 2006 oil spill–preparedness exercising, we simulated spilled pollution by way of freeing hundreds of glide cards at the website of hypothetical spills west of San Francisco. The consequences of this observe are to be had on an in advance, archived model of our website. Our flow card FAQ solutions most of the questions that people have asked about flow card releases, and the U.S. Geological Survey has more information and pictures(link is outside) from the drill.

More Information about Drift Card and Ocean Studies
NOAA Global Drifter Program: Drifting buoys, or “drifters,” are seashore ball-sized buoys that you can have seen out within the water. Unlike Argo floats or gliders that dive underwater, drifters glide at the floor of the ocean. Drifters can degree temperature, salinity, sea stage pressure, wind, currents, or even wave houses. There are currently about 1,three hundred drifters in the worldwide ocean as part of the Global Drifter Program. GOMO works with the Scripps Langrangian Drifter Lab(hyperlink is external) (LDL) to expand distinct styles of drifters, and NOAA’s Atlantic Oceanographic and Meteorological Lab (AOML) to installation drifters in scientifically great components of the ocean.
