Abstract The ocean is a sink for ~25% of the atmospheric CO 2 emitted by human activities, an amount in excess petagrams carbon per year (PgC yr −1 ). Time-resolved estimates global ocean-atmosphere flux provide important constraint on budget. However, previous this flux, derived from surface concentrations, have not corrected data temperature gradients between and sampling at few meters depth, or effect cool skin. Here we calculate time history fluxes 1992 to 2018, these effects. These...
Abstract The contemporary air‐sea flux of CO 2 is investigated by the use an equation, with particular attention to uncertainties in global values and their origin respect that equation. In particular, deriving from transfer velocity sparse upper ocean sampling are investigated. Eight formulations gas used evaluate combined standard uncertainty resulting several sources error. Depending on expert opinion, a either ~5% or ~10% can be argued will contribute proportional error flux. limited f...
The strong control that the emissions of carbon dioxide (CO2) have over Earth's climate identifies need for accurate quantification emitted CO2 and its redistribution within Earth system. ocean annually absorbs more than a quarter all this absorption is fundamentally altering chemistry. thus provides fundamental component powerful constraint global assessments used to guide policy action reducing emissions. These rely heavily on satellite observations, but their inclusion often invisible or...
Following the outbreak of severe acute respiratory syndrome coronavirus (SARS-CoV-2), airborne water droplets have been identified as main transmission route. Identifying and breaking all viable routes are critical to stop future outbreaks, potential by has highlighted. By modifying established approaches, we provide a method for rapid assessment risk posed fecally contaminated river give example results 39 countries.

Abstract. The flow (flux) of climate-critical gases, such as carbon dioxide (CO2), between the ocean and atmosphere is a fundamental component our climate an important driver biogeochemical systems within oceans. Therefore, accurate calculation these air–sea gas fluxes critical if we are to monitor oceans assess impact that gases having on Earth's ecosystems. FluxEngine open-source software toolbox allows users easily perform calculations from model, in situ, Earth observation data. original...
Learning to model can be simultaneously exciting and frustrating, people's "first models" often suffer from very similar conceptual technical problems.Sometimes, these are so severe that the seems impossible analyse, can't generate interpretable results, or simply published.Here, we don't aim teach technicalities of modelling-each field will have its own requirements, idiosyncrasies, conventions, most this is well covered elsewhere (for example, see [1] for an introduction modelling in...
Air–sea gas fluxes are commonly estimated using wind-based parametrizations of the transfer velocity. However, neglecting exchange forcing mechanisms – other than wind speed may lead to large uncertainties in flux estimates and carbon budgets, particular, heterogeneous environments such as marginal seas coastal areas. In this study we investigated impact including relevant processes air–sea CO2 parametrization for Baltic Sea. We used six velocity evaluate effect precipitation, water-side...
Wild animals encounter humans on a regular basis, but vary widely in their behaviour: whereas many people ignore wild animals, some present threat, while others encourage animals' presence through feeding. Humans thus send mixed messages to which must respond appropriately be successful. Some species appear circumvent this problem by discriminating among and/or socially learning about humans, it is not clear whether such strategies are actually beneficial most cases. Using an...
Antigenic diversity is commonly used by pathogens to enhance their transmission success. Within-host clonal antigenic variation helps maintain long infectious periods, whereas high levels of allelic at the population level significantly expand pool susceptible individuals. Diversity, however, not necessarily a static property pathogen but in many cases generated very act infection and transmission, it therefore expected respond dynamically changes immune selection. We hypothesized that this...
Abstract. Large rivers play an important role in transferring water and all of its constituents, including carbon various forms, from the land to ocean, but seasonal inter-annual variations these riverine flows remain unclear. Satellite Earth observation datasets reanalysis products can now be used observe synoptic-scale spatial temporal carbonate system within large river outflows. Here, we present University Exeter (UNEXE) Oceanographic Datasets for Acidification (OceanSODA) dataset...
Infection by the human malaria parasite Plasmodium falciparum results in a broad spectrum of clinical outcomes, ranging from severe and potentially life-threatening to asymptomatic carriage. In process naturally acquired immunity, individuals living malaria-endemic regions build up level protection, which attenuates infection severity an exposure-dependent manner. Underlying this shift immunoepidemiology as well observed range pathogenesis is var multigene family phenotypic diversity...
Analogies are a fundamental part of our cognition and communication. Humans also social species with shared cultural repertoires learnt throughout lifetimes. As such, we expect analogies to enable the learning complex, novel information by communication that takes advantage information. Here, demonstrate plausibility this proposal clarify its scope through computational modelling. We first model individual-level process via analogy access repertoire information, using NK landscapes represent...

We present simple use automated workflow for georectifying individual aerial images using position orientation from drone's on-board sensor (i.e....
