Physical, chemical, and biological data from lagoons and open coastal waters in the nearshore environment of the eastern Alaska Beaufort Sea, 2011-2013

Data from discrete water samples, benthic grabs and trawls, plankton tows, and in-situ sensors were collected along the eastern Alaska Beaufort Sea coast, between the Hulahula River delta (144.190 degrees West) and Demarcation Bay (141.267 degrees West) were collected between 2011 and 2013. The first sampling trip was conducted in August 2011. Samples were collected during April (through ice), late June early July (during ice break-up), and August (open water) in 2012 and 2013. HOBO data loggers for temperature and salinity were deployed during the August 2011 trip and recorded ~2.5 years of continuous data over the course of the project. Samples/data were collected at six lagoon sites (Kaktovik Lagoon, Jago Lagoon, Tapkaruk Lagoon, Angun Lagoon, Nuvagapak Lagoon, and Demarcation Bay), and four open water sites along the coastline (Hulahula, Bernard Point Dew Line, Bernard Spit, and Demarcation Point). Separate excel spreadsheets are provided for discrete water samples, biota stable isotope values, YSI sonde measurements, and HOBO data loggers. A "Metadata" tab is included in each spreadsheet with details about the specific datasets that that they contain.

本数据集采集于阿拉斯加博福特海东部沿岸，覆盖范围介于胡拉ula河三角洲（西经144.190°）与分界湾（西经141.267°）之间，采集源包括离散水样、底栖采泥器（benthic grabs）采样、底拖网采样、浮游生物拖网以及原位传感器（in-situ sensors）监测数据，采集时段为2011年至2013年。首次采样航次于2011年8月开展；2012年与2013年的采样分别于4月（冰下作业）、6月末至7月初（融冰期）以及8月（无冰敞水期）进行。2011年8月的航次部署了HOBO温度盐度数据记录仪（HOBO data loggers），该设备在整个项目周期内连续记录了约2.5年的观测数据。本次采样共设置6个泻湖站点：卡克托维克泻湖（Kaktovik Lagoon）、哈戈泻湖（Jago Lagoon）、塔普卡鲁克泻湖（Tapkaruk Lagoon）、安贡泻湖（Angun Lagoon）、努瓦加帕克泻湖（Nuvagapak Lagoon）及分界湾（Demarcation Bay），以及4个沿岸敞水站点：胡拉ula河、伯纳德点远程预警线（Bernard Point Dew Line）站点、伯纳德斯皮特岬（Bernard Spit）及分界点（Demarcation Point）。本数据集提供4个独立的Excel电子表格，分别对应离散水样、生物稳定同位素值、YSI多参数水质监测仪（YSI sonde）测量数据以及HOBO数据记录仪监测数据。每个电子表格均包含“元数据（Metadata）”工作表，用于详细说明该表格所包含的具体数据集信息。
