You can find out where the majority of the Niemann families were living before they immigrated to the U.S and learn where to focus your search for foreign records. Immigration records can tell you an ancestor's name, ship name, port of departure, port of arrival, and destination.from the New York Passenger Lists.iemann census records. Census records can offer a lot of little known facts about your Niemann ancestors, such as occupation. Occupation can tell you about your ancestors' social status and economic status.
Ooze, pelagic (deep-sea) sediment of which at least 30 percent is composed of the skeletal remains of microscopic floating organisms. Oozes are basically deposits of soft mud on the ocean floor. They form on areas of the seafloor distant enough from land so that the slow but steady deposition of dead microorganisms from overlying waters is not obscured by sediments washed from the land.
Siliceous ooze is a siliceous pelagic sediment that covers large areas of the deep ocean floor. Siliceous oozes consist predominantly of the remains of microscopic sea creatures, mostly those of diatoms and radiolarians.Sometimes siliceous oozes also contain silicoflagellates and the spicules of sponges.1  Diatoms are golden-brown algae that construct an opaline silica microscopic shell that is known as a  frustule 2  . Silicoflagellates are a minor group of marine algae that construct microscopic shells composed of opaline silica.hese conditions exist within areas of high biological productivity associated with volcanic islands and nutrient-rich upwelling zones. As the least common type of pelagic sediment, it covers only 15% of the ocean floor. It accumulates at a slower rate than calcareous ooze: 0.2â1 cm / 1000 yr.
