Bed level data of Advancing Resilience Measures for Vegetated Coastlines (ARM4VEG), Guyana

This collection contains data collected during mangrove-mudflat campaign in Guyana, during the PhD Thesis project of Uwe Best. It is being made public both to act as supplementary data for publications and the final PhD thesis document, as well as to allow for open usage by other researchers in their own work. This dataset covers the bathymetric Survey of the Intertidal Area, Chateau Margot Coastline, Guyana during Dec 2019 - Jan 2020. It also captures the development of the bed over a mudbank cycle (~ 20 - 30 years). Within the mangroves, a combination of traditional surveying techniques were used with the automatic level and theodolite. Within the mangroves, limited satellite coverage prevented the use of the DGPS. A permanent bench mark (PBM) was established and used to setup the eleven transects along the field area (1000 m x 3500 m). Along the mudflat, the depths were attained using an echo sounder. boat itself. These measurements were taken over four days to complete ten (10) transects. In November/December 2003 lines were surveyed with a spacing of 2 km (in offshore blocks). In May/June 2004 the intermediate lines were surveyed. The measured depths were corrected using measured water levels at Georgetown. The bed level measurements were supplemented by the global bathymetric charts for the years 2004, 2008 and 2019.本数据集收录了乌韦·贝斯特（Uwe Best）博士论文项目期间，在圭亚那开展红树林-潮滩野外科考所获取的实测数据。本次公开数据集的目的，一是为相关学术论文及最终博士学位论文提供补充数据支持，二是供其他科研人员在其研究工作中开放使用。 本数据集覆盖2019年12月至2020年1月期间，圭亚那玛戈堡（Chateau Margot）海岸线潮间带区域的水深测量工作，同时记录了潮滩周期（约20-30年）内的床面演变过程。 在红树林区域内，本次调查采用自动水准仪与经纬仪结合的传统测量技术；由于该区域卫星信号覆盖有限，无法使用差分全球定位系统（DGPS）。研究人员设立了永久基准点（PBM），以此为基准在1000米×3500米的野外调查区域内布设了11条样带。 在潮滩区域，研究人员通过搭载于作业船只的回声测深仪获取水深数据，本次测量耗时四天，共完成10条样带的数据采集。 2003年11月/12月，研究人员对间距为2千米的近海区块测线开展了测量；2004年5月/6月，完成了中间过渡测线的测量工作。所测得的水深数据通过乔治敦站点实测水位数据进行了校正。床面高程测量数据还补充了2004年、2008年及2019年的全球水深图数据。
