Narrative Documents

Pro Oceanus CO₂-Pro Submersible pCO₂ Sensor

An in-situ dissolved gas sensor measuring the partial pressure of CO₂ (pCO₂) gas dissolved in water using infrared detection. An internal zeroing feature provides a stable long-term baseline for ensuring accurate and stable measurements. The CO₂-Pro can also be modified to measure both water and air pCO₂. Standard ranges from 0-600 ppm to 0-2000 ppm.

Full specifications can be found in the sensor data sheet.

Processing by BODC of PAP1 Mooring Pro-Oceanus CO2-Pro CV data: JC165

The PAP1 mooring was deployed on June 4, 2018 by the RRS James Cook cruise JC165. The data from the Pro-Oceanus sensors were supplied to BODC in a .csv (ASCII) file. The data were then loaded into BODC's database using established BODC data banking procedures with no changes. For more information see the cruise report.

The originator variables were mapped to appropriate BODC parameter codes as follows:

The reformatted data were visualised using in-house EDSERPLO software. Any suspect data were flagged using the BODC quality control flags.

Processing by Originator of PAP1 Mooring Pro-Oceanus CO2-Pro CV Data: JC165

The following was taken from the JC165 cruise report and originator's files. For more detailed information please refer to the cruise report.

A self-logging Pro-OCeanus CV CO2 sensor was deployed on the frame. It was configured to take readings twice a day (every 12 hours).

Project Information

Marine LTSS: CLASS (Climate Linked Atlantic Sector Science)

Introduction

CLASS is a five year (2018 to 2023) programme, funded by the Natural Environment Research Council (NERC) and extended until March 2024.

Scientific Rationale

The ocean plays a vital role in sustaining life on planet Earth, providing us with both living resources and climate regulation. The trajectory of anthropogenically driven climate change will be substantially controlled by the ocean due to its absorption of excess heat and carbon from the atmosphere, with consequent impacts on ocean resources that remain poorly understood. In an era of rapid planetary change, expanding global population and intense resource exploitation, it is vital that there are internationally coordinated ocean observing and prediction systems so policy makers can make sound evidence-based decisions about how to manage our interaction with the ocean. CLASS will underpin the UK contribution to these systems, documenting and understanding change in the marine environment, evaluating the impact of climate change and effectiveness of conservation measures and predicting the future evolution of marine environments. Over the five-year period CLASS will enhance the cost-effectiveness of observing systems by migrating them towards cutting edge autonomous technologies and developing new sensors. Finally, CLASS will create effective engagement activities ensuring academic partners have transparent access to NERC marine science capability through graduate training partnerships and access to shipborne, lab based and autonomous facilities, and modelling capabilities.

Data Activity or Cruise Information

Data Activity

Moored Instrument Rig PAP1_062018

This rig was deployed as part of the Porcupine Abyssal Plain (PAP) observatory project. 'PAP1_062018' refers to the deployment of mooring number 1 in June 2018 ('062018') located at the PAP Observatory.

Data summary

Instrumentation

The mooring design is an 'S' tether configuration allowing the mooring to better withstand the extremes of the environment it is in. The main surface buoy is an ODAS (Ocean Data Acquisition System) buoy, and below this buoy are 30 metres of chain with a conducting cable running along side. The chain is there to take the loads that the mooring will experience and the cable is a vehicle for the data. Attached to the bottom of the chain is the instrument frame, and coming out of the bottom of the frame is a cable attached to a subsurface buoy, an acoustic release and then finally a 3 tonne sinker weight. Further details on page 21 of the deployment cruise report.

Instruments on the subsurface frame are listed below:

Fixed Station Information

Fixed Station Information

Porcupine Abyssal Plain (PAP) Observatory

The Porcupine Abyssal Plain (PAP) observatory is a site at which moorings were deployed in the Northeastern Atlantic, as part of the ANIMATE (Atlantic Network of Interdisciplinary Moorings and Time-series for Europe), MERSEA (Marine Environment and Security for the European Area), EuroSITES, Oceans2025, Fix03 and CLASS projects. The PAP site is centred at latitude 49° N and longitude 16.5° W. Moorings have occupied this region since 2002 and are typically deployed for 12 months.

Please note: Near Real Time data is only stored at BODC where delayed mode data were not recovered. All near real time data can be found at the OceanSites GDA and through IFREMER.
