Lahjat mereltä


Tänä jouluna USGS Yhdysvaltain geologian tutkimuskeskus (United States Geological Survey) tarjoaa katsottavaksi suuren määrän upeita valokuvia ja videoita merenpohjalta ja rantaviivalta.

Useimpia näitä meri- ja rannikkoalueiden kuvauksia ei ole koskaan ennen nähty tai kartoitettu yksityiskohtaisesti tällä tasolla, se on suurin tietokanta lajissaan.

Aluksi 4 kuvaa maistiaisiksi. Portaalista löytyy valtava määrä kuvia, joita voi suurentaa ja tutkia tarkasti. Myös hyvät paikka- ja muut tiedot jokaisesta kuvasta. (Linkki portaaliin jutun lopussa)


Photograph showing the seafloor off the California coast. This photograph supports the California Seafloor Mapping Program (CSMP), a cooperative program established in 2007 initiated by state and federal agencies, academia and private industry. Data collected during this project reveal the seafloor offshore of the California coast in unprecedented detail and provide an ecosystem context for the effective management of this precious marine resource.

This photograph of the seafloor off the Massachusetts coast shows a lobster, sponges and brachiopods on cobbles and ledge covered with seaweed, bubblegum algae and red filamentous algae. The photograph was collected as part of USGS research in collaboration with the Massachusetts Office of Coastal Zone Management to support development of the Massachusetts Ocean Management Plan and management of the state’s waters.

This photograph shows ice-wedge polygons and an eroding shoreline at Cape Halkett on the Beaufort Sea coast of Alaska. Coastal erosion along the Arctic coast is chronic, widespread and potentially accelerating, posing threats to infrastructure important for defense and energy purposes, natural shoreline habitats and nearby Native communities. To help address these concerns, the USGS is collecting information on past and present shoreline changes along the conterminous United States and parts of Alaska and Hawaii.
