Particle Filtering for Source Depth and Water Depth Joint Tracking in Shallow Water

open access: yesJournal of Marine Science and Engineering, 2023
Environmental mismatch degrades the performance of source localization and tracking methods in shallow water. One solution is to estimate source parameters and the key environmental parameters simultaneously from the acoustic data.

Relating the depth of the water table to the depth of weathering

open access: yesEarth Surface Processes and Landforms, 2020
AbstractWeathering of bedrock creates and occludes permeability, affecting subsurface water flow. Often, weathering intensifies above the water table. On the contrary, weathering can also commence below the water table. To explore relationships between weathering and the water table, a simplified weathering model for an eroding hillslope was formulated

Passive Source Depth Discrimination in Deep-Water [PDF]

open access: yesIEEE Journal of Selected Topics in Signal Processing, 2019
This paper addresses the problem of passive source depth discrimination in ocean acoustics using a horizontal line array (HLA). The scope is restricted to low-frequency sources (frequency $f  Hz), broadband signals (bandwidth $B$ of a few Hz), deep-water environment (water depth $D>\text{1000}$  m), and distant sources (range $r$ greater ...

Feeding Habits and the Occurrence of Anthropogenic Debris in the Stomach Content of Marine Fish from Pattani Bay, Gulf of Thailand

open access: yesBiology, 2022
This study assessed the feeding habits and ingestion of anthropogenic debris in 34 marine fish species from the southern Gulf of Thailand. A total of 5478 fish samples of 12 families were categorised into seven groups: planktivore, Lucifer feeder, fish ...

Water Depth Influences the Head Depth of Competitive Racing Starts

open access: yesInternational Journal of Aquatic Research and Education, 2011
Recent research suggests that swimmers perform deeper starts in deeper water (Blitvich, McElroy, Blanksby, Clothier, & Pearson, 2000; Cornett, White, Wright, Willmott, & Stager, 2011). To provide additional information relevant to the depth adjustments swimmers make as a function of water depth and the validity of values reported in prior literature ...
