Reconstructing Global Chlorophyll-a Variations Using a Non-linear Statistical Approach.
(2020)
Monitoring the spatio-temporal variations of surface chlorophyll-a concentration (Chl, a
proxy of phytoplankton biomass) greatly benefited from the availability of continuous and
global ocean color satellite measurements ...
Monitoring protocol for coastal reefs. Version 1.0.
(The Long-term Ecological Research Program Coastal Habitats of Espírito Santo (LTER HCES), Vitória, Brazil, 2020)
The aim of this protocol is to elucidate the methodology and rationale applied in the Long-Term Research Program for Coastal Habitats in Espírito Santo to monitor marine biodiversity in coastal reefs of the Eastern Brazil ...
Improved Calibration and Data Processing Procedures of OPUS Optical Sensor for High-Resolution in situ Monitoring of Nitrate in Seawater.
(2021)
Nitrate, an essential nutrient for primary production in natural waters, is optically
detectable in the ultraviolet spectral region of 217–240 nm, with no chemical reagents
required. Optical nitrate sensors allow monitoring ...
Motus Wave Sensor 5729, TD 316 Operating Manual, 3rd edition.
(Aanderaa Data Instruments AS, Bergen, Norway, 2020)
This document is intended to give the reader knowledge of how to operate and maintain the Aanderaa Motus Wave Sensor 5729. The sensor is made for integration with either EMM 2.0 buoy or Motus DB 1750 buoys or used as ...
Fishing Gear as a Data Collection Platform: Opportunities to Fill Spatial and Temporal Gaps in Operational Sub-Surface Observation Networks.
(2020)
While the observation of the open ocean is well achieved by automated ocean
measurement instruments, coastal and shelf seas suffer the lack of sub-surface
collection platforms. Commercial fishing gear such as bottom ...
Salish Sea Ambient Noise Study: Best Practices. (2021).
(Vancouver Fraser Port Authority, Enhancing Cetacean Habitat and Observation (ECHO) Program, Vancouver, Canada, 2021)
All monitoring locations and hydrophone systems have unique features that affect the ability to monitor ambient noise levels accurately. As anthropogenic underwater noise effects on marine species becomes increasing important ...
Driven by Drones: Improving Mangrove Extent Maps Using High-Resolution Remote Sensing.
(2020)
This study investigated how different remote sensing techniques can be combined to accurately monitor mangroves. In this paper, we present a framework to use drone imagery to calculate correction factors which can improve ...
Nonintrusive methods for biomass estimation in aquaculture with emphasis on fish: a review.
(2020)
Fish biomass estimation is one of the most common and important practices in
aquaculture. The regular acquisition of fish biomass information has been identified
as an urgent need for managers to optimize daily feeding, ...
Long-term intercomparison of two pCO2 instruments based on ship-of-opportunity measurements in a dynamic shelf sea environment.
(2021)
The partial pressure of carbon dioxide (pCO2) in surface seawater is an important biogeochemical variable
because, together with the pCO2 in the atmosphere, it determines the direction of air–sea carbon dioxide
exchange. ...
Video demonstrating how to set-up, deploy and operate a shallow-water drop camera system. [Training video]
(Octopi Africa (Pty) Ltd and Array Media (Pty) Ltd, Cape Town, South Africa, 2021)
Drop cameras are simple frame-deployed systems of various configurations that are designed to take photographic still images or videos of the seafloor. These tools are non-destructive and can go to beyond SCUBA depths, ...
