Surface waves and their interactions with sediments and benthic organisms are the main hydrodynamic process affecting littoral ecosystems. Here, we present a long-term data set on surface-wave parameters, which was obtained from the analysis of measurements with a pressure sensor. The data set covers a time period of a year and allows for resolving waves with heights down to less than a centime...

The long-term goal of this project is to derive a general and comprehensive algorithm to calculate a scalar image metric which will help quantify the performance of emerging laser-based imaging systems in the highly variable optical littoral environment. After validation, this image metric will then be used to assist in mission planning by providing up-to-date maps of the expected system perfor...

Acoustic signal transmissions in littoral regions can have as much as 15 to 20 dB variability due to spatial and temporal effects [1]. Recent studies have shown that the ambient noise levels in the littoral also exhibit high variability that may be correlated to the littoral environment. Since both signal and noise variability have a direct impact on sonar system performance, an initial goal of...

This study quantifies the role of lake morphometry and submerged macrophyte beds on the accumulation of sediments in the littoral zone. Stable Pb, a historical marker of lacustrine sediments in southern Quebec, was used to date the sediments (;110 yr) and to calculate three long-term sediment accumulation rates (SARs) in Lake Memphremagog (located in Quebec and Vermont). The anthropogenic Pb bu...

The physical structure of vegetation influences diversity, interactions, movement, and thermoregulation of animals. Vegetation structure might be a good indicator of habitat requirements of generalist predators, such as dragonflies and damselflies (order Odonata), and thereby affect species diversity. Odonates use aquatic and terrestrial habitats during larval and adult life stages, respectivel...

The spatial distribution and patterns of habitat use of littoral fish species in Lake Constance were studied using electric fishing and trammel net sampling to assess fish abundance and biomass in three depth strata at six different sampling sites within the littoral zone. Distribution differences among depth strata were found to be often more pronounced than among different sampling sites. Juv...

there are two species of ghost shrimps namely, neocallichirus jousseaumei, n. calmani of which the latter is the first record for the persian gulf (littoral and subtidal zones). while, n. jousseaumei is first record for littoral zones along coastal waters of the persian gulf. the material of present study was collected from ouli village along the coast of bushehr province. here, notes on habita...
