Atmospheric conditions were recorded by three meteorological towers at PIE-LTER. Wind speed (m s-1) and temperature (deg C, T15min) were measured 14 m above the marsh (42.742 deg N, 70.830 deg W). Wind speed was scaled to 10m height (wnd10). Photosynthetically active radiation (PAR15min; umol m-2 s-1) was recorded by two towers that were deployed at different times between May-November (42.724 deg N, 70.856 deg W and 42.739 deg N, 70.827 deg W).Raw benthic chlorophyll and phaeophytin data from each experimental time point in June, August, and October 2013.

Instruments

Air Temperature Sensor

Supplied Name: Temperature sensor

Supplied Description:

Measured air temperature

Instrument Type

Generic Name: Air Temperature Sensor

Acronym: AirTemp

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0283/

Generic Description:

Measures air temperature

Photosynthetically Available Radiation Sensor

Supplied Name: PAR sensor

Supplied Description:

Recorded by two towers that were deployed at different times between May-November

Instrument Type

Generic Name: Photosynthetically Available Radiation Sensor

Acronym: PAR sensor

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/122/

Generic Description:

A PAR sensor measures photosynthetically available (or active) radiation. The sensor measures photon flux density (photons per second per square meter) within the visible wavelength range (typically 400 to 700 nanometers). PAR gives an indication of the total energy available to plants for photosynthesis. This instrument name is used when specific type, make and model are not known.

Vector-Averaging Wind Recorder

Supplied Name: Wind speed measured

Supplied Description:

Wind speed (m s-1) and temperature (deg C, T15min) were measured 14 m above the marsh. Wind speed was scaled to 10m height.

Instrument Type

Generic Name: Vector-Averaging Wind Recorder

Acronym: VAWR

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/101/

Generic Description:

The Vector-Averaging Wind Recorder (VAWR) is a system designed by researchers at Woods Hole Oceanographic Institution (WHOI) to make surface meteorological measurements. The standard WHOI Vector Averaging Wind Recorder (VAWR) of the late 1980s through early 1990s was mounted on a toroid buoy (Dean and Beardsley, 1988). In addition to wind speed and direction, the VAWR could also be configured to record water temperature and conductivity data from sensors mounted at 1 meter depth on the mooring bridle of the buoy (Trask et al., 1995).
