Science objectives

Background: In recent years there has been increasing interest and emphasis placed on
developing and fielding unmanned systems to support Intelligence, Surveillance and
Reconnaissance (ISR) mission areas. The Navy Strategic Plan, Defense Planning Guidance and
other Program Objective Memorandum guidance cite an urgent need to employ unmanned
systems in forward operating areas and augment Carrier/Expeditionary Strike Group and
Theater ISR assets. Systems fielded under the CNO Littoral Battlespace Sensing . Unmanned
Undersea Vehicle (UUV) program have significantly increased dimensional oceanographic
sensing capability and capacity in support of Undersea Warfare (USW); leading to significant
changes in operational TTP and UUV employment.
The Naval Oceanography Program is poised to expand its unmanned systems portfolio to
include UAV- and USV- based sensing capabilities in support of optimized sensor employment,
improved maritime forecasting, UxV platform mission planning and environmental hazard
avoidance and mitigation, and rapid hydrographic survey operations. The availability of high
resolution UxV-based METOC observations, typically in data sparse or contested areas, will
inevitably lead to significant changes in fleet TTPs.
Science Objectives: Utilize observations from unmanned air, surface, and undersea vehicles
(UxVs) to assess the impact of in-situ observations on the representation and prediction of the
Ocean Battlespace Environment and subsequent tactical impact on predictions of the
electromagnetic (EM) propagation characteristics in the coastal marine atmospheric boundary
layer.

Science Activities

Planned Observing Platforms (July 13-18):
- 5 days on station R/V Knorr  (sfc met, sst, current profiles, single station
rawinsondes and sfc fluxes)
-50 ScanEagle UAV Flight Hours (~10 sorties @50 Kts) (met profiles, sfc wave lidar)
-4 Waveglider USVs (sfc met, sst, current profiles)
-5 Scripps drifting wave buoys (sfc wave spectra)
-1 to 2 NPS Flux Buoys (sfc met, sfc fluxes)
-6 to 10 SLOCUM Seaglider UUVs (ocean temp, salinity, optical profiles)
- R/V Knorr single station VHF/UHF/SHF/EHF radio range, power, SNR observations.
- 288 High density P3 dropped AXBT observations before/during/after TW’13 Intensive
Observation Period (IOP)

Aircraft Sensing (POC: Lenain (SIO), Melville(SIO), Eber(NSWCDD))
Specific flight profiles for best sampling strategy against likely synoptic and mesoscale
regimes and refractivity features.
Aircraft can fly between 100-15,000 ft at ~50 kts for up to 10 hours, day or night. Typical
mission day is 2 x 5hr flights. 1-Hz data resolution is ~90 ft horiz/ 10 ft vertical.
Measured variables (realtime: lat/lon/ht, t, p, q, u, v, time) (stored onboard: imagery,
wave spectra, turbulence data, 40 Hz state variables)
Comms link is ~25 NM if aircraft is near the surface, farther at altitude. (need to check
comms range)

Ocean Sensing(POC:Shearman (OSU) Melville (UCSD) Terrill (SIO) Davis (SPAWAR))
5 moored wave buoys (directional wave spectra)
4 Waveglider¨SHARC¨ USVs with sfc met and ADCP current sensors (Tair, Tsea, q, p,
U, V, currents (z))
6-10 SLOCUM Gliders (T(z), S(z), currents (z), Fluorescence (z)).
Airborne eXpendable BathyThermographs on NRL P-3 288 AXBTs will be deployed on
4 flights (72 per flight). AXBTs transmit 1 W on the VHF sonobuoy channels between
136.0-173.5 MHz
