EN4: Quality controlled ocean temperature and salinity profiles and monthly objective analyses with uncertainty estimates Tập 118 Số 12 - Trang 6704-6716 - 2013
Simon Good, Matthew J. Martin, Nick A Rayner
We present version 4 of the Met Office Hadley Centre “EN” series of data sets of
global quality controlled ocean temperature and salinity profiles and monthly
objective analyses, which covers the period 1900 to present. We briefly describe
the EN4 data sources, processing, quality control procedures, and the method of
generating the analyses. In particular, we highlight improvements relative to

cBathy: A robust algorithm for estimating nearshore bathymetry Tập 118 Số 5 - Trang 2595-2609 - 2013
R. A. Holman, Nathaniel G. Plant, Todd Holland
A three‐part algorithm is described and tested to provide robust bathymetry maps
based solely on long time series observations of surface wave motions. The first
phase consists of frequency‐dependent characterization of the wave field in
which dominant frequencies are estimated by Fourier transform while
corresponding wave numbers are derived from spatial gradients in cross‐spectral
phase over ana... hiện toàn bộ
Hindcast and validation of Hurricane Ike (2008) waves, forerunner, and storm surge Tập 118 Số 9 - Trang 4424-4460 - 2013

Powell, Vincent J. Cardone, Andrew T. Cox, Hasan Pourtaheri, Hugh J.R. Roberts, J. H. Atkinson, S. Tanaka, H. J. Westerink, L. G. Westerink
Hurricane Ike (2008) made landfall near Galveston, Texas, as a moderate
intensity storm. Its large wind field in conjunction with the Louisiana‐Texas
coastline's broad shelf and large scale concave geometry generated waves and
surge that impacted over 1000 km of coastline. Ike's complex and varied wave and
surge response physics included: the capture of surge by the protruding

River‐tide dynamics: Exploration of nonstationary and nonlinear tidal behavior in the Yangtze River estuary Tập 120 Số 5 - Trang 3499-3521 - 2015
Leicheng Guo, Mick van der Wegen, David A. Jay, Pascal Matte, Zheng Bing Wang, Dano Roelvink, Qing He
AbstractRiver‐tide dynamics remain poorly understood, in part because
conventional harmonic analysis (HA) does not cope effectively with nonstationary
signals. To explore nonstationary behavior of river tides and the modulation
effects of river discharge, this work analyzes tidal signals in the Yangtze
River estuary using both HA in a nonstationary mode and continuous wavelet
transforms (CWT). The... hiện toàn bộ
Anticyclonic Eddies Connecting the Western Boundaries of Indian and Atlantic Oceans Tập 123 Số 11 - Trang 7651-7677 - 2018
Rémi Laxenaire, Sabrina Speich, Bruno Blanke, Alexis Chaigneau, Cori Pegliasco, Alexandre Stegner
AbstractThe Indo‐Atlantic interocean exchanges achieved by Agulhas Rings are
tightly linked to global ocean circulation and climate. Yet they are still
poorly understood because they are difficult to identify and follow. We propose
here an original assessment on Agulhas Rings, achieved by TOEddies, a new eddy
identification and tracking algorithm that we applied over 24 years of satellite
altimetr... hiện toàn bộ
Variability of Circumpolar Deep Water transport onto the Amundsen Sea Continental shelf through a shelf break trough Tập 118 Số 12 - Trang 6603-6620 - 2013
Karen M. Assmann, Adrian Jenkins, Deborah R. Shoosmith, Dziga P. Walker, Stanley S. Jacobs, Keith W. Nicholls
The presence of warm Circumpolar Deep Water (CDW) intrusions on the Amundsen
continental shelf has been linked to recent thinning of the outlet glaciers
draining the West Antarctic ice sheet into the Amundsen Sea. Inflow of the CDW
onto the shelf is thought to occur within a series of troughs that intersect the
continental shelf break. We use observations between 1994 and 2011 and a
numerical mode... hiện toàn bộ
Mapping Dependence Between Extreme Rainfall and Storm Surge Tập 123 Số 4 - Trang 2461-2474 - 2018
Wenyan Wu, Kathleen L. McInnes, Julian O’Grady, Ron Hoeke, Michael Leonard, Seth Westra
AbstractDependence between extreme storm surge and rainfall can have significant
implications for flood risk in coastal and estuarine regions. To supplement
limited observational records, we use reanalysis surge data from a hydrodynamic
model as the basis for dependence mapping, providing information at a resolution
of approximately 30 km along the Australian coastline. We evaluated this
approach ... hiện toàn bộ
Physical controls on hypoxia in Chesapeake Bay: A numerical modeling study Tập 118 Số 3 - Trang 1239-1256 - 2013
Malcolm E. Scully
ABSTRACTA three‐dimensional circulation model with a relatively simple dissolved
oxygen model is used to examine the role that physical forcing has on
controlling hypoxia and anoxia in Chesapeake Bay. The model assumes that the
biological utilization of dissolved oxygen is constant in both time and space,
isolating the role that physical forces play in modulating oxygen dynamics.
Despite the simpl... hiện toàn bộ
