Ship Request

STR Management has moved to MFP

The US Academic Research Fleet is moving to Marine Facilities Planning (MFP) for scheduling initially and eventually cruise planning.

For all NEW or RESUBMITTED Projects/Ship Time Requests, go to and create a new SME. Some STRs for projects starting in 2022 and beyond have already been moved to Marine Facilities Planning ( Check your MFP Science Portal for any projects that might already be moved. If you need to make edits to projects that begin in 2022 and beyond, please contact for assistance. Be sure to indicate the Project and STR IDs that you would like to edit. For more information on getting into MFP, see the More Information button below.

Project Title: Spectral Energy Dissipation in Broad-banded Wave Fields Project Status: Submitted
Principal Investigator: James M. Thomson, UW_APL Project Institution: UW_APL
Project ID: 102148 Version #: 1
Date Submitted: 8/10/2009 6:46:00 PM Created By: James M. Thomson
Date Last Modified: 9/17/2012 7:50:00 PM URI Serial #: None
Funding Agencies: NSF/OCE/PO - 0960778 - Funded
Summary of Field Work: Two field experiments are proposed to make simultaneous remote and in situ measurements of
energy dissipation rates in broad-banded wave fields. The experiments will expand incrementally
from prior results measuring of narrow-banded wave fields. During the winter of year 1, a 10-day
experiment on onboard the R/V Robertson (APL-UW) will be conducted in the Juan de Fuca
Strait, WA. Conditions are expected to be moderate (wave heights less than 2 m), and the goal will
be to test new measurement techniques prior to an open ocean experiment. The 10-day duration is
sufficient to cover a range of wave and weather conditions, based on data from NDBC station 46088.
During the autumn of year 3, a 20-day experiment onboard a UNOLS vessel will be conducted in
the North Pacific Ocean. The duration is necessary to observe a range of wave conditions, including
variations in wave age, which has a much larger range (0 to 10) in the open ocean than in semi-
enclosed bodies of water. Wave heights up to 5 m are targeted for this experiment. The R/V
Thompson at UW is requested to minimize shipping and logistical costs and shared ship time
will be possible.

Shipboard instrumentation from previous efforts on Lake Washington and Puget Sound will be
redeployed, including a visual camera and sonic wave gage and Dopbeam beam velocity profilers,
corrected for motion using a three-axis accelerometers. In addition, two new platforms, a wave-
following float and a 'helikite' aerostat, are proposed to support measurements in open ocean
conditions. The new platforms are necessary to capture the larger spatial scales of open ocean waves,
and have the added advantage of avoiding the hull-reflections common to shipboard measurements.
Summary of Facility Requirements: Shipboard video and met data via 10 m tower,
Regular deployment and recovery of small free drifting buoys, and
Regular deployment and recover of tethered 'helikite' aerostat.
Summary of other requirements and comments: Ability to modify route in realtime as wave conditions dictate.

Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations:
Thomas G. Thompson is requested to minimize mobilization/shipping costs, if Seattle port call is possible. Request could be changed to "collaborative" if other users can accommodate 10 days of surveying in a variety of wave conditions (including transit to find desired wave conditions).
