Seals at sea: modelling seal distribution in the German bight based on aerial survey data [PDF]

open access: yes, 2009
The Wadden Sea is an important habitat for harbour seals and grey seals. They regularly haul-out on sandbanks and islands along the coast. Comparably little is known about the time seals spend at sea and how they use the remainder of the North Sea.

Looking beyond stratification: a model-based analysis of the biological drivers of oxygen deficiency in the North Sea [PDF]

open access: yes, 2016
Low oxygen conditions, often referred to as oxy- gen deficiency, occur regularly in the North Sea, a temperate European shelf sea. Stratification represents a major process regulating the seasonal dynamics of bottom oxygen, yet, low- est oxygen ...

PIA : more accurate taxonomic assignment of metagenomic data demonstrated on sedaDNA from the North sea [PDF]

open access: yes, 2020
Assigning metagenomic reads to taxa presents significant challenges. Existing approaches address some issues, but are mostly limited to metabarcoding or optimized for microbial data. We present PIA (Phylogenetic Intersection Analysis): a taxonomic binner

Recent changes in the surface salinity of the North Atlantic subpolar gyre [PDF]

open access: yes, 2002
Sea surface salinity (SSS) was measured since 1896 along 60°N between Greenland and the North Sea and since 1993 between Iceland and Newfoundland. Along 60°N away from the shelves, and north of 53°N, the amplitude of the seasonal cycle is comparable to ...

Histological investigations on the thyroid glands of marine mammals (Phoca vitulina, Phocoena phocoena) and the possible implications of marine pollution [PDF]

open access: yes, 1993
In 1988 and 1989, thousands of harbor seals (Phoca vitulina) died in the North Sea from phocine distemper infection. The morphology of thyroid glands from 40 harbor seals found dead on the North Sea coastlines of Schleswig-Holstein, Federal Republic of ...

Variability of the winter wind waves and swell in the North Atlantic and North Pacific as revealed by the Voluntary Observing Ship data [PDF]

open access: yes, 2006
This paper analyses secular changes and interannual variability in the wind wave, swell, and significant wave height (SWH) characteristics over the North Atlantic and North Pacific on the basis of wind wave climatology derived from the visual wave ...

Formation and propagation of great salinity anomalies [PDF]

open access: yes, 2003
North Atlantic/Arctic ocean and sea ice variability for the period 1948–2001 is studied using a global Ocean General Circulation Model coupled to a dynamic/thermodynamic sea ice model forced by daily NCEP/NCAR reanalysis data [Kalnay et al., 1996 ...

Theory and Practice of Handling Issues Left over from the History of Sea Reclamation Based on the Thought of Ecological Civilization: Taking Taiping Bay Port Area of Dalian Port and Sino-Singapore Tianjin Eco-City as Examples

open access: yesHaiyang Kaifa yu guanli, 2022
Long-term and large-scale reclamation activities have not only revitalized the economy of coastal areas, but also severely damaged coastal ecosystems. This paper sorted out a series of policy requirements and technical guidelines on strengthening coastal
