Havbundssediment 250.000

Kortet viser havbundens strukturer og fordelingen af sedimenter i den øverste halve meter af havbunden. Kortet dækker hele den danske eksklusive økonomiske zone (EEZ området). Sediment typerne i kortet er bestemt ud fra sammensætningen af kornstørrelser i sedimentet. Dog er Moræne/diamict et blandet sediment og Sedimentært grundfjeld indikere hvor det flere millioner år gamle grundfjeld stiger op til overfladen. Fordelingen af sedimenter afspejler de geologiske processer både i fortiden og i nutiden. Da de punkter hvor der er indsamlet data er ujævnt fordelt og i visse områder ganske spredt, er fortolkningen til dels baseret på ekstrapolation og ikke mindst på faglige vurderinger. Denne udgave af kortet er generaliseret til visning i 1:250.000, der findes en udgave af kortet der har alle kortlagte detaljer med. Kortet er beskrevet i Geoviden 2014, nr. 2

This release makes available the West Canadian Coast part of the results of an ongoing effort to scan and convert all our inventory of analog marine survey field records (seismic, sidescan and sounder) to digital format. These records have been scanned at 300 dpi and were converted into JPEG2000 format. Typically each of these files were from 1 to 2 gbyte in size before compression, and were compressed by a factor of 10:1. Empirical tests with a number of data sets suggest that there is minimal visual distortion of the scanned data at this level of compression. In this KML file, scanned data are available in a reduced-scale thumbnail format and a compressed full-resolultion JPEG2000 format.

Maricolous sites

Mariculture includes several different types of activities in public marine territory, such as the cultivation and harvesting of seaweed, the harvesting of green urchins, and the breeding of blue mussels or scallops, among others. Each of these activities has very distinct environmental, physicochemical and biological needs, in addition to having to coexist safely with other human activities and constraints in the maritime environment. For these reasons, mariculture activities must take place in delimited and reserved marine areas, and therefore require a permit. The “Maricolous Sites” data set brings together under provincial coverage (polygons) the information contained in the permits issued by the regional directorates. It identifies businesses, and presents their permit numbers, types of activities and species that they are authorized to raise, as well as the location and area of sites (polygons) under permits and authorizations to operate a mariculture site issued by MAPAQ.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**
