Intra-annual salinity and temperature variation in four regions across latitude (Competition and Predation across Latitude)

Abstract:

Temperature and salinity measurements from coastal sites across a latitudinal gradient spanning the subarctic to the tropics. Environmental variables were obtained at 1 meter below the water surface and are represented in biweekly periods for one year.

Description

Methods & Sampling

Methodology:

Environmental variables were obtained from three coastal sites in each of four regions at 1 meter below the water surface. Sites were recreational marinas selected to conduct experiments on marine invertebrate communities. Temperature and salinity measurements were collected from each site for a minimum of one year. Monitoring began in Alaska in June 2015, California in May 2016, Mexico in June 2017 and Panama in December 2015.

Sampling and analytical procedures:

Three HOBO temperature data loggers were deployed at each site to record water temperature every hour for the one-year sampling period. Minimum, maximum and mean temperatures were calculated in biweekly periods. Salinity measurements were recorded biweekly from four standardized locations at each site and averaged.

Instruments

Multi Parameter Portable Meter

Supplied Name: ProQuatro handheld multiparameter meter, YSI

Supplied Description:

Salinity measurements were recorded biweekly from four standardized locations at each site and averaged.

Instrument Type

Generic Name: Multi Parameter Portable Meter

Generic Description:

An analytical instrument that can measure multiple parameters, such as pH, EC, TDS, DO and temperature with one device and is portable or hand-held.

Onset HOBO Pendant Temperature/Light Data Logger

Supplied Name: HOBO Pendant, Onset, Model UA-002-08

Supplied Description:

Three HOBO temperature data loggers were deployed at each site to record water temperature every hour for the one-year sampling period.

Instrument Type

Generic Name: Onset HOBO Pendant Temperature/Light Data Logger

Acronym: Onset HOBO Pendant Temp/Light

Generic Description:

The Onset HOBO (model numbers UA-002-64 or UA-001-64) is an in-situ instrument for wet or underwater applications. It supports light intensity, soil temperature, temperature, and water temperature. A two-channel logger with 10-bit resolution can record up to approximately 28,000 combined temperature and light measurements with 64K bytes memory. It has a polypropylene housing case. Uses an optical USB to transmit data. A solar radiation shield is used for measurement in sunlight. Temperature measurement range: -20 deg C to 70 deg C (temperature). Light measurement range: 0 to 320,000 lux. Temperature accuracy: +/- 0.53 deg C from 0 deg C to 50 deg C. Light accuracy: Designed for measurement of relative light levels. Water depth rating: 30 m.

Refractometer

Supplied Name: Salinity Handheld Refractometer

Supplied Description:

Salinity measurements were recorded biweekly from four standardized locations at each site and averaged.

Instrument Type

Generic Name: Refractometer

Generic Description:

A refractometer is a laboratory or field device for the measurement of an index of refraction (refractometry). The index of refraction is calculated from Snell's law and can be calculated from the composition of the material using the Gladstone-Dale relation.

In optics the refractive index (or index of refraction) n of a substance (optical medium) is a dimensionless number that describes how light, or any other radiation, propagates through that medium.
