Water levels in meters from four wells in Moneystump marsh at Blackwater National Wildlife Refuge, MD. Two wells are located in the upland forest; one well is located in the marsh-forest transition zone (ecotone); and one well is located in the marsh. Water depth of the adjacent creek is reported in meters. Data covers the time span from November 11 2016 - November 11 2017. Pressure transducer data from the wells corrected to water level using barometric pressure loggers located in 3 locations throughout the experiment. Water levels are in units of meters referenced to vertical datum NAVD88. Raw pressure data is in units of kilopascals (kPa). Pressure transducer locations and elevation data from GNSS and digital laser level survey leveraging local deep rod SET benchmark SO5A is also included.Light intensity levels in lux was obtained from 25 light sensors (HOBO UA-002 HOBO Pendant Waterproof Temperature/Light Data Logger), five sensors are located in the lowest elevation (marsh), five located in the upper marsh, five located in the marsh-forest transition zone (ecotone), five located in the lower forest, and five located in the highest elevation (upper forest). Light data covers the time span from October 1 2015 - September 30 2019. Light intensity levels in lux from upper sensors in Moneystump marsh at Blackwater National Wildlife Refuge MD. There are 25 light sensors all located in the control treatment area. Five sensors are located in the lowest elevation (marsh), five located in the upper marsh, five located in the marsh-forest transition zone (ecotone), five located in the lower forest, and five located in the highest elevation (upper forest). Data covers the time span from October 1 2015 - September 30 2019.
