Long-Term Real-Time Coastal Ocean Observation Networks
Coastal Ocean Observation Long-Term Real-Time
2015/8/5
Oceanographers are well acquainted with the challenges of working in an undersampled ocean, Observations are often sparse, difficult or expensive to acquire, and may not even be available to the sea-g...
Operational Observation Networks for Ports, a Large Estuary and an Open Shelf
Open Shelf Ports
2015/8/5
This paper describes the goals, capabilities and accomplishments of three operational coastal ocean observation networks. In the companion paper in this volume, the authors discuss reasons for the rap...
Implementation of the South Atlantic Bight Synoptic Offshore Observation Network
Synoptic Offshore Observation Network South Atlantic
2015/8/5
Continuous information on coastal ocean conditions in the South Atlantic Bight (SAB), provided by an interdisciplinary real-time coastal ocean observing network, is now accessible. Many applications a...
Observation, Hypothesis-Testing, and Discovery in Oceanography
Oceanography Hypothesis-Testi
2015/7/29
Discovery lies at the very heart of scientific endeavor. It heralds progress, the march of science in uncovering the mysteries of the world that surrounds us. But how do discoveries come about? "By ob...
An Overview of Fixed Passive Acoustic Observation Methods for Cetaceans
Cetaceans Acoustic Observation Methods
2015/7/22
Cetaceans are increasingly being included as top trophic-level predators in models of ecosystem dynamics (Baumgartner and Mate, 2003; Tynan, 2004; Redfern et al., 2006). Traditional visual survey meth...
Observation of the Structure on Moving Gust Patterns Over a Water Surface (“Cat's Paws”)
Moving Gust Patterns Water Surface
2009/4/2
We report on observations of near-surface Velocity, temperature, stress, buoyancy, and surface wave fluctuations, including successive short-time averages of coherences, phases, autospectra, and proba...
Geoelectromagnetic observation at the seafloor—Present and future
seafloor geoelectromagnetic observation natural-source magnetotellurics controlled-source
2009/3/5
It has been almost three decades since geoelectromagnetic observation at the seafloor was enabled. The objective of this article is to make an overview of the present status of the seafloor electroma...
Observation and Simulation of Storm-Induced Mixed-Layer Deepening
mixed-layer Storm-Induced Mixed-Layer Deepening
2009/2/23
Two observed cases of mixed-layer (ML) deepening due to storms are analyzed and simulated. The primary goal is to learn whether the relevant scale velocity in the parameterization of wind-driven deepe...
Observation of a Baroclinic Eddy：An Example of Mesoscale Variability in the Bering Sea
Baroclinic Eddy Bering Sea Mesoscale Variability
2009/2/18
Drift buoys with shallow (17 m) drogues, released during May 1977 and tracked by satellite, delineated an eddy in the southeastern Bering Sea. Located above complex topography having a depth range of ...
From current meter and satellite data, an unusual pattern of movement of the Gaspe Current was identified on two occasions in the summer of 1978. On the first occasion, the axis of the current moved o...
Observation of the Power Spectrum of Ocean Waves Using a Cloverleaf Buoy
Power Spectrum Ocean Waves Cloverleaf Buoy
2009/2/16
The power spectra of typical sets of ocean wave data obtained in the open ocean using a cloverleaf buoy are analyzed to determine an idealized form for the spectrum of ocean surface waves. It is shown...
Observation and Modeling of Satellite-Sensed Meanders and Eddies off Vancouver Island
Satellite-Sensed Meanders Vancouver Island
2009/1/19
A long time series of satellite infrared images spanning the period 21 July–8 October 1980 reveals the evolution of long (160 km) and short (80 km) wavelength meanders of the California Current System...
A Three-Dimensional Simulation of the Hudson–Raritan Estuary. Part II：Comparison with Observation
Three-Dimensional Simulation Hudson–Raritan Estuary Comparison with Observation
2009/1/16
Results from a time-dependent, three-dimensional numerical simulation of the Hudson–Raritan estuary are compared with observations. The comparison includes: 1) instantaneous salinity contours across a...
Observation of an Anticyclonic Eddy near the Continental Shelf Break South of New England
Anticyclonic Eddy Continental Shelf New England
2009/1/10
A small scale but energetic and highly nonlinear anticyclonic eddy was observed near the New England Shelf Break in July 1983. Satellite images show a tongue of shelf water 15 km wide flowing offshore...
