Other ID: T-M1-09-AR

Status: Completed

Organization(s): USGS, Pacific Coastal and Marine Science Center

Funding Program(s): Arctic bluff retreat (MU012)

Principal Investigator(s): Li Erikson, Curt Storlazzi

Affiliate Investigator(s):

Information Specialist(s): Li Erikson

Data Type(s): Location-Elevation: Navigation, Environmental Data: Wave, Environmental Data: Current, Environmental Data: CTD, Time Series: Mooring (physical oceanography), Location-Elevation: LIDAR, Sampling: Geology, Environmental Data: Temperature, Environmental Data: Sediment Properties

Scientific Purpose/Goals: To obtain baseline measurements and support research contributing to the development of a predictive model of Arctic bluff retreat and inundation of barrier islands due to the a changing global climate on the North Slope of Alaska.


Start Port/Location: Barrow, Alaska

End Port/Location: Barrow, Alaska

Start Date: 2009-08-11

End Date: 2009-08-26

Equipment Used: RTK GPS, Nortek AWAC, microCat, AWAC, CTD 19+ with OBS, PAR, DO, Chl, LIDAR, hand auger, thermistor, penetrometer, torvane

Information to be Derived: Waves, currents, bathymetry, sediment and bluff characteristics, suspended sediment flux, salinity and temperature, and beach and bluff topography.

Summary of Activity and Data Gathered: Collected bathymetry, elevation (foreshore), grain size (bluffs), and CTD casts.

Staff: Gerry Hatcher, Jim Allen, Thomas Reiss

Affiliate Staff:
Brian Collins (Earth Surface Processes
USGS) - Terrestrial LIDAR
Mark Savoie (Kinnetics Laboratories
Inc.) - Boat captain
Moses Nayakik - Wainwright resident

Notes: mooring AIN09F1T. Shop time includes the design and construction of bottom mounts specifically designed for the North Slope. Deployment of Trawl Resistant Bottom Mount deployed Aug. 10-25. TRBM to be recovered Sept. 22-25, 2009 Platforms used: Two vessels, ATVs, and by foot. Deployment, recovery of bottom-mounted instruments, and collection of data pertaining to bathymetry, sediments, and bluff characteristics. Study of Arctic bluff retreat and inundation of an ecologically sensitive barrier island system due to a changing global climate.
