Transport of trace metals in nearshore sediments
… interface and within the sediment column of nearshore sediments. The early diagenesis of several first-row transition metals exhibiting a variety of behaviors in the ocean -- Mn, Fe, Co, Ni, and Cu -- has been studied intensively at a site in Buzzards Bay, Mass. By limiting the study to a …

Modeling of nearshore hydrodynamics for sediment transport calculations
This thesis analyzes and improves Tajima's (2004) nearshore hydrodynamic model. Tajima's simple model accurately predicts long-shore sediment transport along long, straight beaches, while cross-shore transport predictions differ from observations. A better prediction of cross-shore transport …

Nearshore sediment dynamics in a mixed sand/mud environment
… show the channel area passes through the beach nearshore zone, and during the monitoring period maintenance dredging only maintained the channel design depth along the channel leads, while significant infilling occurred near the channel edges (Δh = -1 m). Extrapolation of the results suggests an …

The responses of subtropical nearshore fishes to climate change
… expected to increase in intensity and frequency. Nearshore ecosystems serve as critical habitat for juvenile fishes (e.g., schoolmaster snapper, yellowfin mojarra) and function as foraging grounds for adults (e.g., bonefish, checkered puffer), yet it is unclear how nearshore fishes will respond to …

Collaboration within the Puget Sound Marine and Nearshore Scientific Community
… researchers studying Puget Sound marine and nearshore ecosystems in order to inform recovery. The collaboration network structure, derived from 253 online surveys, is explained and contextualized using 20 qualitative key-informant interviews. The scientific network involved in Puget Sound …

The nearshore dynamics of Matroos Bay : field and theoretical investigations
… and theoretical investigations were made of the nearshore circulation of Matroos Bay, a small embayment on the south-western coast of Africa. The field study revealed two dominant circulation types, denoted "anticlockwise" and "clockwise". The anticlockwise circulation type was characterized by …

Modeling sandbar effects on nearshore waves and morphological change using SWAN
… outer sandbar (in about 5-m water depth) on the nearshore wave field as the shallow (< 3 m) bathymetry changes from near alongshore uniform to strongly spatially variable to understand wave driven morphologic evolution. Waves were observed at Duck, NC with an array of 14 pressure gages between 1- …

Distribution and abundance of nearshore aquatic habitat, Fraser River, British Columbia
… investigates the effects of space and time on nearshore aquatic habitat in the gravel reach of Fraser River, British Columbia by employing a large river, stage-adaptive habitat classification system. The distribution and abundance of habitat are spatially quantified at the reach scale (32 km), …

Nearshore Bathymetry from Fusion of ICESat-2 and Multispectral Satellite Imagery
… global need for accurate and frequently updated nearshore bathymetry data sets. Airborne lidar bathymetry (ALB) is the most accurate way to survey large areas with high accuracy, although these data collections are limited by their high cost and by turbidity in some places. High resolution …

Movement of Selected Nearshore Temperate Reef Fishes Along California's Central Coast
… regarding the expected outcomes for temperate nearshore fish species, especially the Sebastes genus (rockfishes). Movement behavior of temperate reef-fishes plays an important role in the level of protection that a reserve will afford a species. Consistent small-scale movements (<10 km) and …

Phytoplankton physiology in a nearshore region of the southern Benguela current
During the summer of 1978-79 diatoms dominated the communities from October to January but microflagellates were dominant in February and March. Low concentrations of ATP, chlorophyll a protein and carbohydrate were measured in Type 1 water with protein/carbohydrate ratios being )1. In Type 2 water …

Nearshore and inner shelf sedimentation on the east Coromandel coast, New Zealand
… conditions transporting large quantities of fine nearshore sands seawards onto the inner shelf surface, where they are slowly reworked along the shelf during annual storm events and back onshore during fair weather conditions. This latter onshore return of fine sands is proposed to result from an …

Effects of Posidonia oceanica seagrass on nearshore waves and wave-induced flows.
This work focuses on the effects of the large Mediterranean seagrass Posidonia oceanica on coastal waves and wave-induced flows, which has significant implications for coastal protection. Investigations were made on both a natural shallow Posidonia oceanica bed and, in controlled conditions of …

A multi-indicator approach to dietary assessments within Lake Michigan's nearshore area
Fundamental to understanding species ecology, is the evaluation of predator-prey interaction strengths and their spatial heterogeneity. Traditional dietary assessment methods of examining individual’s stomach contents provide valuable data quantifying relationships, however what is incorporated …

Size-selective sediment transport and cross-shore profile evolution in the nearshore zone
Cross-shore bathymetric evolution in the nearshore zone often leads to threatening consequences such as beach erosion and shoreline retreat that concern the coastal community. A new, comprehensive cross-shore morphodynamic model was developed that can be used to describe and predict these …
