In situ temperature measurements collected at the height of El Niño at Jarvis Island in 2015 and 2016

Abstract:

This dataset contains in situ temperature measurements collected at the height of El Niño on 12-15 November 2015 and after severe El Niño conditions had subsided on 16-24 May 2016 for the west and east sides of Jarvis Island at 7-10 m depth.

Description

Methods & Sampling

Short-term oceanographic instrument deployments were conducted at the same sites on 12-15 November 2015 and 16-23 May 2016. Instrument package deployments included a SAMI-pH sensor (Sunburst Sensors, 15 min sampling interval), SBE-37 Microcat (Sea-Bird Electronics, 20 sec sampling interval), and dissolved oxygen sensor (RBR, 1 min sampling interval) which were affixed to the reef at 7 m (east) and 10 m (west) depth.

Samples were collected during expeditions aboard:

R/V Machias (12–15 November 2015)
NOAA ship Oscar Elton Sette (17–23 May 2016)

Research activities and sample collection were conducted under U.S. Fish and Wildlife Service Pacific Reefs National Wildlife Refuge Complex Research and Monitoring Special Use Permits:

12521-10001 (effective date: 15 Jan 2010; expiration date: 30 May 2010)
12521-12001 (effective date: 7 Feb 2012; expiration date: 31 Dec 2012)

12513-15001 (effective date: 11 Nov 2015; expiration date: 31 Dec 2015)

and in compliance with Presidential Proclamation 8336.

Data Processing Description

All instrument data were processed in R (version 3.0.1).

Instruments

CTD Sea-Bird MicroCAT 37

Supplied Name:

Supplied Description:

SBE-37 Microcat (Sea-Bird Electronics, 20 sec sampling interval)

Instrument Type

Generic Name: CTD Sea-Bird MicroCAT 37

Acronym: CTD MicroCAT 37

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/350/

Generic Description:

The Sea-Bird MicroCAT CTD unit is a high-accuracy conductivity and temperature recorder based on the Sea-Bird SBE 37 MicroCAT series of products. It can be configured with optional pressure sensor, internal batteries, memory, built-in Inductive Modem, integral Pump, and/or SBE-43 Integrated Dissolved Oxygen sensor. Constructed of titanium and other non-corroding materials for long life with minimal maintenance, the MicroCAT is designed for long duration on moorings.

In a typical mooring, a modem module housed in the buoy communicates with underwater instruments and is interfaced to a computer or data logger via serial port. The computer or data logger is programmed to poll each instrument on the mooring for its data, and send the data to a telemetry transmitter (satellite link, cell phone, RF modem, etc.). The MicroCAT saves data in memory for upload after recovery, providing a data backup if real-time telemetry is interrupted.
