Sediment oxygen demand in shallow water habitats around Tampa Bay in the Summers of 2015 and 2016

Sediment oxygen demand and environmental variables were measured with field-deployed metabolism core chambers in various sites around the Tampa Bay area in the summers of 2015 and 2016. Each chamber consisted of a 15.24 cm diameter (20.32 cm length) acrylic tube, capped at the top with a custom-built fitting for water stirring and HOBO logger placement. For each chamber deployed, dissolved oxygen and water temperature data were collected from within the chamber. Light meters were deployed in parallel with the chambers to detect ambient light penetration into the water column. From these data, sediment oxygen consumption (mmol O2/m2/day) was calculated. These measurements can be correlated with average temperature, light, time of day, habitat type, site, and sampling year. These data can also be associated with infaunal abundances and characteristics in a related Tampa dataset (GRIIDC UDI: R4.x262.000:0015).

2015年与2016年夏季，研究团队于坦帕湾（Tampa Bay）周边多个采样点位，利用野外部署式代谢核心腔室（field-deployed metabolism core chambers）测定了沉积物需氧量与各类环境变量。每个腔室均由直径15.24 cm、长度20.32 cm的亚克力管构成，顶部加装定制接头，用于水体搅拌与HOBO记录仪（HOBO logger）的安装。针对每一个部署完成的腔室，采集其内部的溶解氧与水温数据。同步部署光照计与各腔室，以监测环境光照向水体柱的穿透情况。基于上述数据，可计算得到沉积物耗氧量（单位：mmol O₂/m²/天）。上述测定结果可与平均水温、光照强度、时段、生境类型、采样点位以及采样年份进行关联分析。本数据集还可与坦帕湾相关数据集（GRIIDC UDI: R4.x262.000:0015）中的底栖动物丰度及其特征进行关联匹配。
