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 ...
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 ...
Comparison of three quick methods to estimate crab size in the land crabs Cardisoma guanhumi Latreille, 1825 and Ucides cordatus (Crustacea: Brachyura: Gecarcinidae and Ucididae).
(2012)
Quick, reliable and non destructive methods are necessary to estimate size structure on commercial
land crabs, in order to acquire relevant information concerning the health of their populations. Cardisoma guanhumi
and ...
Accurate oxygen measurements on modified Argo floats using in situ air calibrations.
(2016)
Oxygen is an important tracer for biological processes in the ocean. Measuring changes in oxygen over
annual cycles provides information about photosynthesis and respiration and their impact on the carbon cycle.
Long-term, ...
NOAA and BOEM Minimum Recommendations for Use of Passive Acoustic Listening Systems in Offshore Wind Energy Development Monitoring and Mitigation Programs.
(2021)
Offshore wind energy development is rapidly ramping up in United States (U.S.) waters in order to meet renewable energy goals. With a diverse suite of endangered large whale species and a multitude of other protected marine ...
Management of acoustic metadata for bioacoustics.
(2016)
Recent expansion in the capabilities of passive acoustic monitoring of sound-producing animals is providing ex-
pansive data sets in many locations. These long-term data sets will allow the investigation of questions ...
Management and research applications of real-time and archival passive acoustic sensors over varying temporal and spatial scales.
(2009)
Defining the appropriate scale over which to conduct a study in the marine environment is critical to achieving appropriate scientific, management, mitigation and conservation objectives. This paper focuses on applications ...
Redes Colaborativas para o Monitoramento - Microplástico - Guia de práticas para o monitoramento de microplástico em praias arenosas.
(Our Blue Hands, Brazil, 2021)
This monitoring protocol for microplastics on sand beaches is carried out by Our Blue Hands project. It was adapted from the microplastics monitoring methodology of the European Union produced in 2013, from the University ...
Evaluating benthic flux measurements from a gradient flux system.
(2022)
Multiple methods exist to measure the benthic flux of dissolved oxygen (DO), but many are limited by short
deployments and provide only a snapshot of the processes occurring at the sediment–water interface. The gradient
flux ...
Best practice in seabed image analysis for determining taxa, habitat, or substrata distributions.
(Ministry for Primary Industries, Wellington, N.Z., 2020)
This is a review of seabed imaging survey methods and their application in New Zealand, focusing on the deep sea and covering the fields of image acquisition, data extraction from imagery, and data management. The potential ...
