Baltic Sea

Information about the Baltic Sea.

In June 2011 swedish treasure hunters discovered a 200' wide saucer shaped artifact at the bottom of the Baltic Sea.

location

The Baltic Sea is located between Central and Northern Europe. 53 degrees north to 66 degrees north and 10 degrees east and 30 degrees east.

size/animal life,etc.

377,000 sq miles.

There are many fish, mammals, amphibians, etc living in the Baltic Sea.

There is lots of algae, mosses, and lichens in the Baltic Sea.

The Baltic Sea has both fresh salt water sea.

The soil type is sandy.

The weather depends on the wind.

The climate in the Baltic Sea is the winter long and cold and summers are short and warm.

Human made Features/language

Under the Baltic Sea there is a tunnel that links Denmark and Sweden together providing a highway and railroad connecting between Sweden and the Danish mainland (the Jutland Peninsula).


The languages that are spoken are Danish, Estonian,Finnish,Swedish,Russian,English.

religion/political system

the Baltic Sea is christian place.

economic activities/population distrubution

The Baltic Sea is almost completely enclosed and – except for a few areas – shallow. Its waters are renewed very slowly. Its north and northeast extremities are frozen over for part of the year, and salinity levels there are very low. As a result, the marine environment is very vulnerable, particularly to eutrophication – a build-up of nutrients from urban waste water, coastal agriculture, industrial pollution and atmospheric deposition.

Following the end of the Cold War, shipping and trading have resumed in the Baltic on a large scale; passenger and goods transport is now the main economic activity.



The Teutonic Order, a German order of crusaders, left a landlord class and a trading class

as part of an urban population, meaning for example that Riga through much of its history

was a cosmopolitan city, while for a 300 year period the Hanseatic cities of Königsberg, (now

Kaliningrad), Danzig, (Gdańsk), Tallinn, (Reval), Visby, and Kalmar were dominated by

German-speaking populations. Through Russian expansion layers of Slavs were added to the

Germans and Swedes already there. Slavs not only made their imprint on the Southeastern

shores of the Baltic Sea as rulers, military and police, but in order to practice their religion

freely a Slave population of Old Believers settled in the Baltic interior in what is now Latgale.

The Poles on the Southern shores of the Baltic Sea were at times in alliance with the Swedes

and the Lithuanians and at other times were fighting off invasions from Sweden as well as

from neighboring Germans and Russians. Being annihilated 3 times throughout its history as

a nation state through unfriendly alliances between its neighbors a Polish nation managed to

survive mainly through its strong culture, language, and religion.

Religion can be a uniting factor for a nation but can also work the other way. When for

example, Sweden in the 17th century, being fervently protestant, took over Ingermanland and

Karelia Orthodox believers fled to Russia, hence adding to the kaleidoscope of peoples around

the Baltic Sea. In 1809 Sweden lost its Eastern part, Finland, after 700 years of colonization,

but left a Swedish speaking population in the archipelago and in the upper class. Many historic

researchers would today argue that Finland as a separate and respected part of the Russian

empire experienced more freedom than under Swedish tutelage.

natural resources

Eutrophication is a major threat to the Baltic Sea, causing algae blooms and hypoxic bottoms. Ecological engineering methods aiming at help mitigating the nutrient imbalance problems have already been initiated or are being planned in the coastal zones of the Baltic Sea. This includes harvesting of reed, macro algae and blue mussels as nutrient and energy natural resources. The potential and feasibility of such methods to form the basis for sustainable use of natural resources is governed by the ecological, technical, economic and social aspects associated with the whole chain of processes from biomass to end products, e.g. biogas, fertilizers, and wastes. As a first step in a sustainability assessment, we show that biogas production from algae and reed is associated with a net energy benefit. Blue mussels do not result in a net energy benefit if used for biogas production, but represent the most efficient way of removing nutrients. Based on these preliminary results, we suggest that biogas production from reed and macro algae is worthy of further investigation, whereas for blue mussels, an alternative product must be found.
