Description

The parameters TidBitID, Block, TrtGroup, HerbivoreTreat, TempTreat, NutrientTreat are only available for the period 2019-06 to 2019-08.

Methods & Sampling

Temperature data collected by automated temperature dataloggers deployed in the bottoms of intertidal rock tide pools, set to sample at 15 minute intervals. Sensors were secured with screws in rock anchors, and remained submerged in pools at all times.

Latitude and longitude values for each of the tide pools used in the field experiment carried out at Bodega Marine Reserve, Bodega Bay in northern California, USA (38.31633326339228, -123.07227140000002). The locations were collected with a Garmin eTrex handheld GPS, using the WGS84 coordinate system.

TrtGroup - Coding variable for treatment type. A numeric value indicating each of 8 unique combinations of HerbivoreTreat, TempTreat, and NutrientTreat.

HerbivoreTreat - Coding variable for herbivore density treatment (Low or High). The High treatment level contains approximately twice the normal number of mobile grazers (limpets and littorine snails) as unmanipulated pools based on preliminary surveys. The Low treatment pools contained a near-zero number of mobile grazers maintained by repeated visits to the pool to manually pick out mobile grazers.

TempTreat - Coding variable for temperature treatment (Ambient or Warmed). Warmed treatment pools had a 60W heating element that heated the pool during daytime low tides, with a targeted 1-2 degree Celsius increase above ambient temperature conditions. Ambient treatment pools did not have temperature manipulated.

NutrientTreat – Coding variable for nutrient treatment (Control or Increased). The Increased treatment received slow-release nitrogen fertilizer to mimic increased coastal ocean nutrient supply. Control treatments were unmanipulated.

Data Processing Description

HOBOware 3.7.13 was used to download data from the sensors, and data were collated into CSV files using scripts written in R version 3.5.

Onset HOBO TidbiT v2 (UTBI-001) temperature logger

Supplied Name: HOBO Tidbit V2 temperature data loggers

Supplied Description:

HOBO Tidbit V2 temperature data loggers, Onset Computer Corporation, Bourne, Massachusetts, USA.

Instrument Type

Generic Name: Onset HOBO TidbiT v2 (UTBI-001) temperature logger

Acronym: HOBO TidBit v2

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/134/

Generic Description:

A temperature logger that measures temperatures over a wide temperature range. It is designed for outdoor and underwater environments and is waterproof to 300 m. A solar radiation shield is required to obtain accurate air temperature measurements in sunlight (RS1 or M-RSA Solar Radiation Shield). With an operational temperature range between -20 degrees Celsius and +70 degrees Celsius, the TidbiT v2 has an accuracy of +/-0.21 and a resolution of 0.02 degrees Celsius.
