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, ...
Video demonstrating how to set-up, deploy and operate a Baited Remote Underwater Video System. [Training Video]
(Octopi Africa (Pty) Ltd and Array Media (Pty) Ltd, Cape Town, South Africa, 2021)
Baited remote underwater stereo-video systems, or stereo-BRUVs, are minimally invasive sampling tools used to collect data on the diversity, abundance and size of fishes as well as information on the benthic habitat where ...
SIPCO2: A simple, inexpensive surface water pCO2 sensor.
(2017)
Efforts to estimate air-water carbon dioxide (CO2) exchange on regional or global scales are constrained by a
lack of direct, continuous surface water CO2 observations. Sensor technology for the in situ measurement of ...
Integrating ocean observations across body-size classes to deliver benthic invertebrate abundance and distribution information.
(2023)
Invertebrate animals living at the seafloor make up a prominent component of life globally, spanning 10 orders
of magnitude in body size over 71% of Earth’s surface. However, integrating information across sizes and ...
Quantifying 210Po/210Pb Disequilibrium in Seawater: A Comparison of Two Precipitation Methods With Differing Results.
(2021)
The disequilibrium between lead-210 (210Pb) and polonium-210 (210Po) is increasingly
used in oceanography to quantify particulate organic carbon (POC) export from the
upper ocean. This proxy is based on the deficits of ...
Modified FlowCAM procedure for quantifying size distribution of zooplankton with sample recycling capacity.
(2017)
We have developed a modified FlowCAM procedure for efficiently quantifying the size distribution
of zooplankton. The modified method offers the following new features: 1) prevents
animals from settling and clogging with ...
