Automatic plankton image classification—Can capsules and filters help cope with data set shift?

Autor: Jens Floeter, Jan Conradt, André Harmer, Silke Janßen, Rene-Marcel Plonus

Publikováno v: Limnology and Oceanography: Methods. 19:176-195

The general task of image classification seems to be solved due to the development of modern convolutional neural networks (CNNs). However, the high intraclass variability and interclass similarity of plankton images still prevents the practical iden

Publikováno v: Hydrological Processes. 34:4712-4726

Understanding groundwater–surface water (GW–SW) interactions is vital for water management in karstic catchments due to its impact on water quality. The objective of this study was to evaluate and compare the applicability of seven environmental

Growth and Decay of Northwestern Tropical Atlantic Barrier Layers

Autor: Nuno Serra, Aurpita Saha, Detlef Stammer

Publikováno v: Journal of Geophysical Research: Oceans. 126

The growth and decay mechanisms of barrier layers in the northwestern tropical Atlantic are studied by investigating small‐scale processes embedded in the regional circulation of the tropical Atlantic using output from an eddy‐resolving numerical

Impact of Intraseasonal Waves on Angolan Warm and Cold Events

Autor: Peter Brandt, Rodrigue Anicet Imbol Koungue

The intraseasonal variability of the tropical eastern boundary upwelling region in the Atlantic Ocean is investigated using multiyear mooring and satellite data. Pronounced oscillations of alongshore velocity and sea level off Angola at periods of ab

On the Along‐Slope Heat Loss of the Boundary Current in the Eastern Arctic Ocean

Autor: Volker Mohrholz, Sandra Tippenhauer, Myriel Vredenborg, Yueng-Djern Lenn, Igor V. Polyakov, Krissy Reeve, Markus Janout, Kirstin Schulz, Benjamin Rabe, Jens Hölemann, Eugenio Ruiz-Castillo

This study presents recent observations to quantify oceanic heat fluxes along the continental slope of the Eurasian part of the Arctic Ocean, in order to understand the dominant processes leading to the observed along‐track heat loss of the Arctic

Long-term intercomparison of two pCO2 instruments based on ship-of-opportunity measurements in a dynamic shelf sea environment

Macovei, V.; Voynova, Y.; Becker, M.; Triest, J.; Petersen, W.: Long-term intercomparison of two pCO2 instruments based on ship-of-opportunity measurements in a dynamic shelf sea environment. In: Limnology and Oceanography: Methods. Vol. 19 (2021) 1, 37-50. (DOI: /10.1002/lom3.10403)

The partial pressure of carbon dioxide (pCO2) in surface seawater is an important biogeochemical variable because, together with the pCO2 in the atmosphere, it determines the direction of air–sea carbon dioxide exchange. Large-scale observations of

Geothermal Convection and Double Diffusion Based on Profiling Floats in the Black Sea

Here, we revisit the existing concepts of the vertical structure of deep layers in the Black Sea using data from sensors deployed on profiling floats. The deep transition layer (DTL) between 700 and 1,700 m acts as an interface between the baroclinic

Growth response of calcifying marine epibionts to biogenic pH fluctuations and global ocean acidification scenarios

Autor: Laura Margarethe Hennigs, Christian Pansch, Yvonne Sawall, Mildred Jessica Johnson, Marlene Wall

In coastal marine environments, physical and biological forces can cause dynamic pH fluctuations from microscale (diffusive boundary layer [DBL]) up to ecosystem‐scale (benthic boundary layer [BBL]). In the face of ocean acidification (OA), such na

We present an application of generative adversarial networks (GANs) to reconstruct the sea level of the North Sea using a limited amount of data from tidal gauges (TGs). The application of this technique, which learns how to generate datasets with th

Inversions of Estuarine Circulation Are Frequent in a Weakly Tidal Estuary With Variable Wind Forcing and Seaward Salinity Fluctuations

Autor: Hans Burchard, Knut Klingbeil, Xaver Lange

Publikováno v: Journal of Geophysical Research: Oceans. 125

The hydrodynamics in estuaries is mainly governed by the competition between a horizontal density gradient, friction, and wind stress. The sensitivity of the estuarine exchange flow to the wind stress increases in the absence of tides, which is inves
