IWC photo-identification catalogues: draft guidelines.
(International Whaling Commission, Impington, UK, 2017)The International Whaling Commission (IWC) has a history of using data and analyses from photo-identification catalogues to assist with its work. (Within this document the term ‘photo-ID catalogue’ describes a database ... -
Leveraging Uncertainty Quantification to Design Ocean Climate Observing Systems.
(2021)Ocean observations are expensive and difficult to collect. Designing effective ocean observing systems therefore warrants deliberate, quantitative strategies. We leverage adjoint modeling and Hessian uncertainty ... -
Long-term passive acoustic recordings track the changing distribution of North Atlantic right whales (Eubalaena glacialis) from 2004 to 2014.
(2017)Given new distribution patterns of the endangered North Atlantic right whale (NARW; Eubalaena glacialis) population in recent years, an improved understanding of spatio-temporal movements are imperative for the conservation ... -
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 ... -
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 ... -
A methodology to uncertainty quantification of essential ocean variables.
(2022)The goal of this study is to provide a universally applicable procedure for a systematic evaluation of in situ measured data from single sensors regarding quantifying the uncertainty of the measurement results. As ... -
A new method for acquiring images of meiobenthic images using the FlowCAM.
(2018)The purpose of this study was to develop a new method for investigating sediment-inhabiting meiobenthos using the Flow Cytometer And Microscope (FlowCAM). Meiobenthos are widely recognized as a useful indicator for assessing ... -
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 ... -
A numerical framework for modeling fate and transport of microplastics in inland and coastal waters.
(2022)Proliferation of microplastics in rivers, lakes, estuaries, coastal waters and oceans is a major global challenge and threat to the environment, livelihoods and human health. Reliable predictive tools can play an essential ... -
Ocean Optics Protocols For Satellite Ocean Color Sensor Validation, Revision 4. Volume III: Radiometric Measurements and Data Analysis Protocols.
(Goddard Space Flight Space Center, Greenbelt, MD, 2003)Volume III: The chapters of this volume briefly review methods used in the field to make the in situ radiometric measurements for ocean color validation, together with methods of analyzing the data (Chapter 1), detailed ... -
OLCI-based NIR-red models for estimating chlorophyll- <i>a</i> concentration in productive coastal waters—a preliminary evaluation.
(2019)We present here results that demonstrate the potential of the recently launched Ocean and Land Colour Instrument (OLCI) onboard the satellite Sentinel-3A to deliver accurate estimates of chlorophyll-a (chl-a) concentration ... -
Plankton Toolbox User’s Guide: for Plankton Toolbox Version 1.3.2/1.3.3.
(Swedish Meteorological and Hydrological Institute, Gothenburg, Sweden, 2020)Plankton form the base of the food web in most aquatic ecosystems. There is a need to estimate the biomass, abundance and the biodiversity of plankton organisms. Eutrophication, climate change, invasive species and harmful ... -
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 ... -
QWMN Good Modelling Practice Principles.
(State of Queensland Department of Environment and Science, Queensland, Australia, 2018)Best practice modelling reduces model uncertainties and quantitatively and qualitatively documents any uncertainties and assumptions for user transparency. Conversely, poor modelling practices contribute to uncertainties ... -
R language-based methods for revealing taxonomic and functional diversity and tracing process of fish fauna.
