Since its first use in the late 80’s, the term chevron has been employed in numerous studies to describe large U- and V-shaped ridges found in or near shorelines worldwide. Most studies have so far focused on Bahamian chevrons that are exclusively of Late Pleistocene age, and on the supposed Holocene chevrons found in S-Madagascar and Australia. In the Bahamas, these deposits have been [...]

We analysed tide gauges at Dublin port and its environs over the period 1938-2018. With three different tide gauges in the vicinity of the main Dublin port gauge, we merged the data sets and validated them against each other. The recordings of all four tide gauges were found to be in good agreement between 2003-2015, though this was markedly less so from 2016 to the present. We estimate the sea [...]

This study aimed to use the Hydrologic Landscapes as environmental classification method in the Piracicaba, Capivari and Jundiaí river basins, validate and use it as an indicator of water yield and storage areas. The method comprises in the same Information Plan (IP) factors that interact with the hydrological cycle in its terrestrial phase. The state of São Paulo, where most of the area is [...]

Peatlands contain one of the largest stores of terrestrial carbon and exert a considerable influence on the global climate cycle. However, both the magnitude of the peatland carbon pool and the development of this pool through time are poorly constrained. In a recently published article, Nichols and Peteet combine basal radiocarbon dates from palaeoecological studies with previously published [...]

The uptake of machine learning (ML) algorithms in digital soil mapping (DSM) is transforming the way soil scientists produce their maps. Machine learning is currently applied to mapping soil properties or classes much in the same way as other unrelated fields of science. Mapping of soil, however, has unique aspects which require adaptations of the ML algorithms. These features are for example, [...]

Short-lived radionuclides are measured in surface sediment to provide a geochronology for the past century. Age-depth models can be produced from 210Pbex activity-derived sedimentation rates and confirmed by 137Cs and 241Am activities that are result of fallout from nuclear weapon tests and the Chernobyl accident. Different methods of age depth modelling using such data require expertise in lake [...]

Delivering the Sustainable Development Goals (SDGs) requires balancing demands on land between agriculture (SDG 2) and biodiversity (SDG 15). The production of vegetable oils in general, and palm oil in particular, is perhaps the most controversial illustration of these trade-offs. Global annual demand for vegetable oil for food, animal feed and fuel is currently at 210 million tons1 (Mt), with [...]

Humanity may have passed its first climate tipping point and face self-sustained melting of the permafrost for hundreds of years even if all man-made GHG emissions are stopped.

This study presents the meteorological information spanning the last two decades of the end of 19th century (1880-1900) extracted from three Romanian newspapers (România Liberă, Gazeta de Transilvania and Foaia Poporului). It describes the characteristics of the newspaper data included in the database, it offers and overview of the meteorological network and climate picture at that time in [...]

Recent appraisals of the Gaia theory tend to focus on the claim that planetary life is a cybernetic regulator that would self-regulate Earth’s chemistry composition and climate dynamics, following either a weak (biotic and physical processes create feedback loops), or a strong (biological activity control and regulates the physical processes) interpretation of the Gaia hypothesis. Here, we [...]

Predicting flood for any location at times of extreme storms is a longstanding problem that has utmost importance in emergency management. Conventional methods that aim to predict water levels in streams use advanced hydrological models still lack of giving accurate forecasts everywhere. This study aims to explore artificial deep neural networks performance on flood prediction. While providing [...]

This report presents a case study for automatic fish species classification in underwater video monitoring of fish passes. Although the presented approach is based on the FishCam monitoring system, it can be used with any video-based monitoring system. The presented classification scheme in this study, is based on Convolutional Neural Networks that do not require the calculation of any [...]

The genus Tetraselmis (Chlorophyta) includes more than 30 species of unicellular micro-algae that have been widely studied since the description of the first species in 1878. Tetraselmis cordiformis (presumably the only freshwater species of the genus) was discovered recently to form intracellular mineral inclusions, called micropearls, which had been previously overlooked. These non-skeletal [...]
