Aerial Monitoring of Channel Islands national Marine Sanctuary

click for enlarged imageThe National Oceanic and Atmospheric Administration (NOAA) keeps tabs on activity within the Channel Islands National Marine Sanctuary, a region six nautical miles out from five of the Santa Barbara Channel Islands. Once a week, plus some weekends, NOAA staff fly transects over the sanctuary, cruising at 1,000 feet, collecting data and mapping. In the event of an oil spill, they may map the channel every few hours.

The controls, to which Ben Waltenberger (NOAA Physical Scientist) is pointing in the photo, are in the cockpit dash.click for enlarged image Connected to the GPS, a laptop computer has data collection and mapping software. As Ben inputs the data, maps are generated in ArcView.

When there are sightings, specifics about the kind of marine mammal or vessel, and what exactly it is doing, are logged. Two of the laptop touch screens are pictured to the left: the first for recording environmental conditions, the second for specifying the type of whale sited. Below is a generalized map of gray whale migration to the south, which was generated by the computer as sitings data was recorded.
