The Influence of Channel Deepening on Tides, River Discharge Effects, and Storm Surge
Journal of Geophysical Research: Oceans - Tập 126 Số 5 - 2021
Stefan A. Talke, Ramin Familkhalili, David A. Jay
AbstractWe combine archival research, semi‐analytical models, and numerical simulations to address the following question: how do changes to channel geometry alter tidal properties and flood dynamics in a hyposynchronous, strongly frictional estuary with a landward decay in tidal amplitudes? Records in the Saint Johns River Estuary since the 1890s show that tidal r...... hiện toàn bộ
Tide‐Storm Surge Interactions in Highly Altered Estuaries: How Channel Deepening Increases Surge Vulnerability
Journal of Geophysical Research: Oceans - Tập 125 Số 4 - 2020
Ramin Familkhalili, Stefan A. Talke, David A. Jay
AbstractWe develop idealized analytical and numerical models to study how storm surge amplitudes vary within frictional, weakly convergent, nonreflective estuaries. Friction is treated using Chebyshev polynomials. Storm surge is represented as the sum of two sinusoidal components, and a third constituent represents the semidiurnal tide (... hiện toàn bộ
River‐tide dynamics: Exploration of nonstationary and nonlinear tidal behavior in the Yangtze River estuary
Journal of Geophysical Research: Oceans - 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 continu...... hiện toàn bộ
Dynamics of the Carbonate System in the Western Indonesian Seas During the Southeast Monsoon
Journal of Geophysical Research: Oceans - Tập 125 Số 1 - 2020
Faisal Hamzah, Teguh Agustiadi, R. Dwi Susanto, Zexun Wei, Liguo Guo, Zhimian Cao, Minhan Dai
AbstractWe present a unique water column data set of dissolved inorganic carbon (DIC) and total alkalinity (TAlk) from a cruise to the western Indonesian Seas during the southeast monsoon, covering the Karimata Strait, western Java Sea, and Sunda Strait. Salinity‐normalized TAlk (NTAlk) in the surface water ranged 2,297–2,348 μmol kg−1, very cl...... hiện toàn bộ
An operational model for filling the black strips of the MODIS 1640 band and application to atmospheric correction
Journal of Geophysical Research: Oceans - Tập 118 Số 11 - Trang 6006-6016 - 2013
Jun Chen, Tingwei Cui, Changsong Lin
Requirement of minimal signal‐to‐noise ratios of ocean color sensors and uncertainties of ocean color products
Journal of Geophysical Research: Oceans - Tập 122 Số 3 - Trang 2595-2611 - 2017
Lin Qi, Zhongping Lee, Chuanmin Hu, Menghua Wang
AbstractUsing simulations, error propagation theory, and measurements from the Moderate Resolution Imaging Spectroradiometer (MODIS), we determined the minimal signal‐to‐noise ratio (SNR) required for ocean color measurements and product uncertainties at different spatial and temporal scales. First, based on typical top‐of‐atmosphere (TOA) radiance over the ocean, ...... hiện toàn bộ
The Angola Current: Flow and hydrographic characteristics as observed at 11°S
Journal of Geophysical Research: Oceans - Tập 122 Số 2 - Trang 1177-1189 - 2017
Robert Kopte, Peter Brandt, Marcus Dengler, Pedro Cláver Mota Tchipalanga, Marisa Macuéria, Marek Ostrowski
Long‐Term Trend of the Tropical Pacific Trade Winds Under Global Warming and Its Causes
Journal of Geophysical Research: Oceans - Tập 124 Số 4 - Trang 2626-2640 - 2019
Yang Li, Quanliang Chen, Xiaoran Liu, Jianping Li, Nan Xing, Fei Xie, Juan Feng, Xin Zhou, Hongke Cai, Zhenglin Wang
AbstractThe recent intensification of trade winds over the tropical Pacific is the strongest ever observed in the past hundred years. This strengthening trend is of great interest in recent research, but the causes are still unclear. Using two relatively long‐term surface wind data sets, the present research shows that there is an overall strengthening trend of the...... hiện toàn bộ
Clusters, deformation, and dilation: Diagnostics for material accumulation regions
Journal of Geophysical Research: Oceans - Tập 120 Số 10 - Trang 6622-6636 - 2015
Helga S. Huntley, B. L. Lipphardt, Gregg Jacobs, A. D. Kirwan
AbstractClusters of material at the ocean surface have been frequently observed. Such accumulations of material play an important role in a variety of applications, from biology to pollution mitigation. Identifying where clusters will form can aid in locating, for example, hotspots of biological activity or regions of high pollutant concentration. Here cluster stre...... hiện toàn bộ
How Can Phytoplankton Pigments Be Best Used to Characterize Surface Ocean Phytoplankton Groups for Ocean Color Remote Sensing Algorithms?
Journal of Geophysical Research: Oceans - Tập 124 Số 11 - Trang 7557-7574 - 2019
Sasha J. Kramer, David A. Siegel
AbstractHigh‐performance liquid chromatography (HPLC) remains one of the most widely applied methods for estimation of phytoplankton community structure from ocean samples, which are used to create and validate satellite retrievals of phytoplankton community structure. HPLC measures the concentrations of phytoplankton pigments, some of which are useful chemotaxonom...... hiện toàn bộ
