We have assembled and conducted primary quality control on previously publicly unavailable water column measurements of the dissolved inorganic carbon system and associated biogeochemical parameters (oxygen, nutrients, etc.) made on 26 cruises in the subarctic and Arctic regions dating back to 1974. The measurements are primarily from the western side of the Canadian Arctic, but also include data that cover an area ranging from the North Pacific to the Gulf of St. Lawrence. The data were subjected to primary quality control (QC) to identify outliers and obvious errors. -
The Carbon Cycle
The Carbon Cycle Inventories: black text Fluxes: purple arrows Carbon is the currency of life Protein Carbohydrates Nucleic acids All living organisms utilize the same molecular building blocks. Time Scales of Carbon Exchange in the Biosphere 4 places carbon is stored: 1) Lithosphere, 2) Atmosphere, 3) Hydrosphere (Ocean), 4) Terrestrial biosphere The oceans carbon cycle • The main components: – DIC, DOC, PC (includes POC and PIC) • Primary processes driving the ocean carbon cycle: – abiotic: solubility, ventilation, transport; – biotic: photosynthesis, respiration, calcification 1 g C in a sugar cube The ocean holds 50 grams of CO2 for every 1 gram of CO2 in the atmosphere CO2 in the atmosphere ~750,000,000,000,000,000 g C CO2 in oceans ~39,120,000,000,000,000,000 g C Dissolved organic carbon ~700,000,000,000,000,000 g C Living and dead particles ~3,000,000,000,000,000 g C C C O O OO C C O O O O C C O O O O C C O O O O Every year, each person in the US releases ~20 tons of CO2 to the atmosphere, equivalent to the mass of 4 adult elephants, and nearly half (2 elephants) ends up in the ocean.

Chesapeake Bay Trust Hypoxia Project
Chesapeake Bay dissolved oxygen profiling using a lightweight, low- powered, real-time inductive CTDO2 mooring with sensors at multiple vertical measurement levels Doug Wilson Caribbean Wind LLC Baltimore, MD Darius Miller SoundNine Inc. Kirkland, WA Chesapeake Bay Trust EPA Chesapeake Bay Program Goal Implementation Team Support This project has been funded wholly or in part by the United States Environmental Protection Agency under assistance agreement CB96341401 to the Chesapeake Bay Trust. The contents of this document do not necessarily reflect the views and policies of the Environmental Protection Agency, nor does the EPA endorse trade names or recommend the use of commercial products mentioned in this document. SCOPE 8: “…demonstrate a reliable, cost effective, real-time dissolved oxygen vertical monitoring system for characterizing mainstem Chesapeake Bay hypoxia.” Water quality impairment in the Chesapeake Bay, caused primarily by excessive long-term nutrient input from runoff and groundwater, is characterized by extreme seasonal hypoxia, particularly in the bottom layers of the deeper mainstem (although it is often present elsewhere). In addition to obvious negative impacts on ecosystems where it occurs, hypoxia represents the integrated effect of watershed-wide nutrient pollution, and monitoring the size and location of the hypoxic regions is important to assessing Chesapeake Bay health and restoration progress. Chesapeake Bay Program direct mainstem water quality monitoring has been by necessity widely spaced in time and location, with monthly or bi-monthly single fixed stations separated by several kilometers. The need for continuous, real time, vertically sampled profiles of dissolved oxygen has been long recognized, and improvements in hypoxia modeling and sensor technology make it achievable. -

Underway Measurement of Dissolved Inorganic Carbon (DIC) in Estuarine Waters

Underway analyses of DIC are required to describe spatial and temporal changes of DIC in marine systems. In this study, we developed a microvolume flow detection method for the underway determination of DIC in marine waters, using gas-diffusion flow analysis in conjunction with electrical 1 conductivity (EC) measurement. Only an acid carrier reagent (0.2 mol.L− ) and an ultrapure water acceptor are required for the DIC monitoring system. In this system, a sampling loop (100 µL) is used to quantify the injection sample volume, allowing micro-sample volume detection. The water sample reacts with the acid reagent to convert carbonate and bicarbonate species into CO2. The water sample is then carried into a gas-diffusion assembly, where the CO2 diffuses from the sampling stream into the acceptor stream. -

Inorganic carbon is also exchanged 11 between soils and the atmosphere and is important for soil function but inorganic carbon stocks are 12 not measured in many national‐ and continental‐scale soil monitoring networks. Topsoil (0–30 cm) 13 inorganic carbon concentrations were measured at more than 2 000 sites on a regular 16‐km grid as 14 part of the French National Soil Monitoring Network (RMQS: Réseau de Mesures de la Qualité des 15 Sols). We used design‐based statistical methods to calculate unbiased estimates of the mean soil 16 inorganic carbon concentration and total stocks across France and we used model‐based methods to 17 determine the uncertainty of these estimates and to predict the spatial distribution of these 18 quantities. The observations of inorganic carbon were highly skewed and did not conform to 19 standard statistical models. We therefore applied a non‐parametric transform to normalise the data 20 and performed validation of the model that resulted. -

Initial conditions and spin up Appendix: Computation of monthly climatology of u2 1. Introduction The success of OCMIP-2 depends critically upon carefully designed and coordinated sim- ulations of the carbon cycle and related processes. Two important criteria must be met. First, the biogeochemical parameterizations chosen should be the most appropriate to meet the goals of the simulation. These parameterizations should be based upon a careful survey of the literature and modeling experience. The purpose of this document is to describe and justify the parameteriza- tions chosen for OCMIP-2 simulations of chlorofluorocarbons, the solubility pump and common biogeochemistry. This document will be revised or amended at a later date to include designs of simulations of radiocarbon, anthropogenic CO2 uptake and “pulse” inputs of CO2 to the ocean. The second important criterion to be met is that individual modeling groups use the exact same biogeochemical parameterizations. -

These measures have been applied to study water quality, and they specifically can be used to study algal blooms. Blooms are a natural phenomenon that, due to anthropogenic activities, appear to have increased in frequency, intensity, and geographic distribution. This paper aims to provide a systematic analysis of research on remote sensing of algal blooms during 1999–2019 via bibliometric technique. This study aims to reveal the limitations of current studies to analyse climatic variability effect. A total of 1292 peer-reviewed articles published between January 1999 and December 2019 were collected. -

Pollution Biomarkers in the Framework of Marine Biodiversity Conservation: State of Art and Perspectives
water Review Pollution Biomarkers in the Framework of Marine Biodiversity Conservation: State of Art and Perspectives Maria Giulia Lionetto * , Roberto Caricato and Maria Elena Giordano Department of Environmental and Biological Sciences and Technologies (DISTEBA), University of Salento, 73100 Lecce, Italy; [email protected] (R.C.); [email protected] (M.E.G.) * Correspondence: [email protected] Abstract: Marine biodiversity is threatened by several anthropogenic pressures. Pollution deriving from the discharge of chemical contaminants in the sea represents one of the main threats to the marine environment, influencing the health of organisms, their ability to recover their homeostatic status, and in turn endangering biodiversity. Molecular and cellular responses to chemical pollutants, known as biomarkers, are effect-based methodologies useful for detecting exposure and for assessing the effects of pollutants on biota in environmental monitoring. The present review analyzes and discusses the recent literature on the use of biomarkers in the framework of biodiversity conservation. The study shows that pollution biomarkers can be useful tools for monitoring and assessment of pollution threat to marine biodiversity, both in the environmental quality monitoring of protected areas and the assessment of the health status of species at risk. Moreover, key areas of the research that need further development are suggested, such as the development of omics-based biomarkers specifically addressed to conservation purposes and their validation in the field, the extension of the biomarker study to a wider number of endangered species, and the development of organic Citation: Lionetto, M.G.; Caricato, R.; guidelines for the application of the biomarker approach in support to conservation policies and Giordano, M.E. -
