Archive of Single-Beam Bathymetry Data Collected from Select Areas in Weeks Bay and Weeks Bayou, Southwest Louisiana, January 2013

A team of scientists from the U.S. Geological Survey (USGS), St. Petersburg Coastal and Marine Science Center (SPCMSC), collected 92-line-kilometers (km) of dual-frequency single-beam bathymetry data in the tidal creeks, bayous, and coastal areas near Weeks Bay, southwest Louisiana. Limited bathymetry data exist for these tidally- and meteorologically- influenced shallow-water estuarine environments. In order to reduce the present knowledge gap, the objectives of this study were to (1) develop methods for regional inland bathymetry mapping and monitoring, (2) test an inland bathymetry mapping system, in pilot locations, for the purpose of integrating multiple elevation (aerial and terrestrial lidar) and bathymetry datasets, (3) implement inland bathymetry mapping and monitoring in highly focused sites, and (4) evaluate changes in bathymetry and channel-fill sediment storage.
This report contains single-beam bathymetric data collected between January 14 and 18, 2013(USGS Field Activity Number 13CCT01). Data were collected from the R/V Mako (5-m vessel) in water depths that ranged from <1 m to 7.7 m. Locations of data collection ranged from open-bay systems to narrow inland tidal creeks.

美国地质调查局（U.S. Geological Survey, USGS）与圣彼得堡海岸与海洋科学中心（St. Petersburg Coastal and Marine Science Center, SPCMSC）的科研团队，在路易斯安那州西南部威克斯湾（Weeks Bay）周边的潮汐水道、滨海河湾及近岸海域，采集了测线总长92千米的双频单波束测深数据。当前针对这类受潮汐与气象共同影响的浅水河口环境的测深数据较为匮乏。为填补现有数据空白，本研究的目标如下：（1）研发区域内陆测深制图与监测方法；（2）在试点区域测试内陆测深制图系统，以整合多源高程数据（航空与地面激光雷达）及测深数据集；（3）在精准聚焦的点位开展内陆测深制图与监测工作；（4）评估测深变化与河道充填沉积物储量。本报告收录了2013年1月14日至18日采集的单波束测深数据（美国地质调查局野外活动编号：13CCT01）。数据采集作业由“Mako号”科研船（5米级船舶）完成，作业水深范围为小于1米至7.7米。数据采集点位覆盖从开阔海湾系统至狭窄内陆潮汐水道的各类水域。请勿将本数据用于导航用途。
