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, ... -
Advancing best practices for assessing trends of ocean acidification time series.
(2022)Assessing the status of ocean acidification across ocean and coastal waters requires standardized procedures at all levels of data collection, dissemination, and analysis. Standardized procedures for assuring quality and ... -
An Alternative to Static Climatologies: Robust Estimation of Open Ocean CO2 Variables and Nutrient Concentrations From T, S, and O2 Data Using Bayesian Neural Networks.
(2021)This work presents two new methods to estimate oceanic alkalinity (AT), dissolved inorganic carbon (CT), pH, and pCO2 from temperature, salinity, oxygen, and geolocation data. “CANYON-B” is a Bayesian neural network ... -
Bayesian statistics and modelling.
(2021)Bayesian statistics is an approach to data analysis based on Bayes’ theorem, where available knowledge about parameters in a statistical model is updated with the information in observed data. The background knowledge ... -
A benthic substrate classification method for seabed images using deep learning: Application to management of deep-sea coral reefs.
(2023)Protecting deep-sea coral-based vulnerable marine ecosystems (VMEs) from human impacts, particularly bottom trawling, is a major conservation challenge in world oceans. Management processes for these ecosystems are weakened ... -
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 ... -
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 ... -
Comparison of two rapid automated analysis tools for large FTIR microplastic datasets.
(2023)One of the biggest issues in microplastic (MP, plastic items <5 mm) research is the lack of standardisation and harmonisation in all fields, reaching from sampling methodology to sample purification, analytical methods ... -
Creation of a global tide analysis dataset: Application of NEMO and an offline objective analysis scheme.
(2021)The accurate prediction of tides is vital for the operation of many industries, early warning of coastal flooding and scientific understanding of ocean processes. In this paper, we describe the creation method of a global ... -
Developing Autonomous Observing Systems for Micronutrient Trace Metals.
(2019)Trace metal micronutrients are integral to the functioning of marine ecosystems and the export of particulate carbon to the deep ocean. Although much progress has been made in mapping the distributions of metal micronutrients ... -
Digital Twin Earth - Coasts: Developing a fast and physics-informed surrogate model for coastal floods via neural operators.
(Neural Information Processing Systems Foundation, 2021)Developing fast and accurate surrogates for physics-based coastal and ocean models is an urgent need due to the coastal flood risk under accelerating sea level rise, and the computational expense of deterministic numerical ... -
Ecosystem Model Skill Assessment. Yes We Can!
(2016)Accelerated changes to global ecosystems call for holistic and integrated analyses of past, present and future states under various pressures to adequately understand current and projected future system states. Ecosystem ... -
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 ... -
Evaluation of Ocean Color Remote Sensing Algorithms for Diffuse Attenuation Coefficients and Optical Depths with Data Collected on BGC-Argo Floats.
(2020)The vertical distribution of irradiance in the ocean is a key input to quantify processes spanning from radiative warming, photosynthesis to photo-oxidation. Here we use a novel dataset of thousands local-noon downwelling ... -
Guidance Note on the Application of Coastal Modelling for Small Island Developing States.
(National Oceanography Centre, Liverpool, UK, 2020)Small Island Developing States (SIDS) are very diverse, but have something in common: they are all vulnerable to human-induced climate change, but have contributed very little to causing the problem, due to their small ... -
An international intercomparison of stable carbon isotope composition measurements of dissolved inorganic carbon in seawater.
(2019)We report results of an intercomparison of stable carbon isotope ratio measurements in seawater dissolved inorganic carbon (δ13C-DIC) which involved 16 participating laboratories from various parts of the world. The ... -
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 ... -
