USING DEEP CONVOLUTIONAL NEURAL NETWORKS TO CLASSIFY LITTORAL AREAS WITH 3-BAND AND 5-BAND IMAGERY
(Monterey, CA; Naval Postgraduate School, 2020-03)
With the assistance of high-resolution satellites, unmanned aerial vehicles, and fixed camera observation points, coastal change detection and landscape classification are active research areas that have the capability to ...
CHARACTERIZATION OF SURFACE ROUGHNESS ALONG THE ROCKY COASTLINE USING STEREO PHOTOGRAPHY TECHNIQUES
(Monterey, CA; Naval Postgraduate School, 2020-06)
High-resolution images have been used to estimate and characterize the roughness of the rocky seafloor in terms of small-scale roughness and power spectral density. The application of this work is acoustical modeling of ...
BUBBLE CLOUD ACOUSTIC SPECTROGRAPHY IN THE JAMES RIVER ESTUARY
(Monterey, CA; Naval Postgraduate School, 2020-06)
The James River Estuary hosts a salt wedge during its tidal cycle that is typical in estuarine environments but is atypical in its V-shape. Linear frequency-modulated acoustic signals in the 500–5000 Hz range were transmitted ...
I-SPAR BUOY: DESIGN OF A LIGHTWEIGHT SHALLOW WATER AIR-SEA MEASUREMENT PLATFORM
(Monterey, CA; Naval Postgraduate School, 2020-12)
An Inner-shelf SPAR buoy (I-SPAR) for measuring atmospheric fluxes was developed for use in 7–20 m water depth as part of the ONR Coastal Land Air Sea Interaction (CLASI) effort. The design requirements are: 1) measurements ...
RELATIONSHIPS BETWEEN ARCTIC ICE WATER FRACTION AND LOCAL 2D WIND STRESSES AT THE SURFACE OF THE CRYOSPHERE
(Monterey, CA; Naval Postgraduate School, 2021-12)
A study of the Marginal Ice Zone (MIZ) in the Central Arctic was sponsored by the Office of Naval Research (ONR) in 2014. This experiment used clusters of buoys equipped with autonomous sensors. As the 2014 arctic season ...
POROELASTIC PROPERTIES FOR MODELING THE WATER-SEDIMENT INTERFACE IN THE NORTHEASTERN SOUTH CHINA SEA
(Monterey, CA; Naval Postgraduate School, 2020-03)
The transmission of underwater sound and its interactions with the sediment layer of the ocean floor has impacts across many areas of naval warfare. There are numerous physical parameters influencing acoustics at the ...
IDENTIFYING SEDIMENT TRANSPORT POTENTIAL AND VELOCITY PROFILES IN THE CARMEL RIVER USING AN ADP
(Monterey, CA; Naval Postgraduate School, 2020-12)
The Carmel River runs 58 km from the Santa Lucia Mountains through the Carmel Valley, eventually stopping at a lagoon on Carmel River State Beach. During the winter months, the river breaches through the lagoon, allowing ...
SPATIAL DISTRIBUTION AND DIRECTIONALITY OF ACOUSTIC SCATTERING IN ROCKY ENVIRONMENTS
(Monterey, CA; Naval Postgraduate School, 2020-12)
The interaction of sound, or an acoustic signal, with the seafloor is an active area of research due to its importance for naval applications in undersea warfare, mine warfare, and special operations, and for remote sensing ...
MODELING THE EFFECTS OF WAVES AND BREACH GEOMETRY ON THE HYDRODYNAMICS OF A BAR-BUILT ESTUARY ALONG CALIFORNIA’S COAST
(Monterey, CA; Naval Postgraduate School, 2021-12)
Bar-built estuaries are found all over the world as a result of ocean waves and rivers colliding and establishing a coastal barrier that can open and close intermittently. These uncertain morphological and hydrodynamic ...
WAKE DETECTION USING CONVOLUTIONAL NEURAL NETWORKS
(Monterey, CA; Naval Postgraduate School, 2021-12)
Advances in engineering and technology have made acoustic detection of submarines increasingly difficult. Using hydrodynamic signatures created by propagating submarines is an alternative method for submarine detection. ...
