Satlantic {Sea-Bird} OCR-507 ICSA multispectral radiometer

A cosine-response radiometer designed for multiwavelength measurements of irradiance for in-air use. The instrument uses silicon photodiodes as detectors and a custom low-fluorescence interference filter. The standard version comes with 7 customer defined channels that measure wavelengths in the bandwidth from 400 to 700 nm. The radiometer has a sampling rate of 7 to 24 Hz and a spectral bandwidth of 10 or 20 nm. An optional bioshutter is available to decrease biofouling on the optical faces of the sensor. Bandwith range can be customised. Typical Noise Equivalent Irradiance (NEI) is 2.5 x 10-3 uW cm-2 nm-1.

Processing by BODC of PAP1 Moored Satlantic Sea-Bird OCR-507 ICSA multispectral radiometer: DY116

The data were supplied to BODC in a single .CSV file and were converted to the BODC internal NetCDF format using standard BODC processing procedures. The variables provided in the .CSV file were mapped to BODC parameter codes as follows:

The reformatted data were visualised using the in-house EDSERPLO software. Suspect data were marked by adding an appropriate quality control flag.

Sampling Strategy

The RRS Discovery cruise DY116 departed Southampton on 10th November 2020 and returned to Southampton on 27th November 2020. A Satlantic OCR-507 ICSA Irradiance sensor with Bioshutter (S/N: 201) was deployed in upward-looking configuration on the Porcupine Abyssal Plain (PAP) PAP1 Mobilis buoy mast in the Northeast Atlantic (49°N, 16.5°W) at 4m above sea level to record irradiance. The sensor was set to sample every 30 minutes at 17 and 47 past the hour, sampling at 1Hz for 2 minutes. The sensor has 7 wavelengths to match satellites: 412, 443, 490, 510, 555, 670, 683 nm.

The PAP1 buoy was recovered on 1st April 2021 on RRS Discovery cruise DY130, and irradiance data collected between 21st November 2020 and 19th February 2021 were processed.

DY116 Cruise report

Further information can be found in the DY116 Cruise report.

Data Acquisition and Initial Processing

The sensor data has not been corrected and it was last calibrated by the manufacturer in September 2017. No data were recorded after 13:17 on 19th February 2021 - this was has been attributed to a suspected failure of the buoy controller power supply. The processed data were supplied to BODC for processing.

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_112020

This rig was deployed as part of the Porcupine Abyssal Plain (PAP) observatory project. 'PAP1_112020' refers to the deployment of mooring number 1 in November 2020 ('112020') located at the PAP Observatory.

Data summary

Instrumentation

The Discovery Cruise DY116 deployed for the first time a Mobilis buoy. The new Mobilis buoy was deployed without a sensor frame. All instruments, except Star Oddi sensors, were deployed attached directly to the buoy. Using cable ties and gaffer tape, Star Oddi sensors were attached at various depths to the rope leading to the anchor. Further details on pages 27, 28, and 56-60 of the deployment cruise report.

Instruments on the buoy 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, CLASS, and AtlantiS 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.
