Conventional wisdom about mesoscale eddies is that cyclonic (anticyclonic) eddies are commonly associated with cold(warm) surface cores. Nevertheless, plenties of surface warm cyclonic eddies (WCEs) and cold anticyclonic eddies (CAEs) in the North ...

The Greenland–Scotland Ridge in a Changing Ocean: Time to Act?
ABSTRACT The Greenland–Scotland Ridge is a submarine mountain that rises up to 500 m below the sea surface and extends from the east coast of Greenland to the continental shelf of Iceland and across the Faroe Islands to Scotland. The ridge not only separates deeper ocean basins on either side, that is, the North Atlantic and Arctic oceans, but also ...

ABSTRACT During the fifteenth and sixteenth centuries, there was no statutory difference between cartography, drawing and painting. These activities were performed then by craftsmen who were part of a vast group under the umbrella of ‘mechanical arts’ and fell under the ‘artifex’ category. Artifex were experts in any particular art, whether a craftsman,

A High-Precision Method for Evaluating the Similarity of Maritime Vessel Trajectories
This study investigates the demand for high-precision trajectory similarity assessment in intelligent maritime navigation. This is done by analyzing discrepancies between GPS-derived trajectories and actual vessel paths, while identifying critical ...

ABSTRACT Visualizing and communicating flood inundation depth and extent can be valuable for informing decisions related to flood preparedness and disaster response. In the United States, several different types of flood inundation mapping (FIM) exist and a new National Water Model (NWM) FIM product is being rolled out across the country (expected to ...

The influence of rivers on seabird foraging ecology
ABSTRACT Rivers act as vital arteries to the world's oceans, delivering fresh water and nutrients that sustain marine ecosystems. Globally, river flow increasingly is being altered by climate change and anthropogenic pressures; yet the significance of rivers to predatory marine species, such as seabirds, and the extent to which river‐related changes ...

A Self-Adaptive Compression Method for Ship Trajectories without Threshold Setting
Addressing the shortcomings of existing ship trajectory compression methods that rely on the empirical setting of a fixed threshold and face challenges in controlling the spatial similarity before and after compression, this paper proposes a self ...
