The document titled 'Exploring Marine Sediments Using Google Earth' by Kristen St. John provides a comprehensive guide for understanding marine sediments through interactive exploration using Google Earth. It includes procedures for examining sediment types, their distribution, and the factors influencing these patterns. The document is divided into three parts: an introduction to marine sediments, exploration of sediment distribution, and refinement of hypotheses regarding biogenic sediment distributions. It emphasizes hands-on learning through observation and data analysis from various marine research programs.

How do you collect marine sediments?

Coring. Corers are used for collecting sediment from the ocean floor; they work by pushing or grabbing sediment into containers. The National Marine Equipment Pool has eight different types of corer with both tubular and box varieties available.

What is a marine sedimentary environment?

Marine sedimentary environments are all found in the ocean. Sediments accumulate rapidly on continental margin (neritic) and slowly in the deep ocean (pelagic). Since there is very little erosion that occurs in the ocean, these sediments provide a good record of ocean and global history.

What sediments are in the ocean?

There are four types: lithogenous, hydrogenous, biogenous and cosmogenous. Lithogenous sediments come from land via rivers, ice, wind and other processes. Biogenous sediments come from organisms like plankton when their exoskeletons break down. Hydrogenous sediments come from chemical reactions in the water.

What are sediments in the aquatic ecosystem?

Aquatic sediment refers to a mixture of clays, silts, organic matter, and other particles found at the bottom of bodies of water. These sediments can contain various minerals and organic materials that interact with dissolved substances, influencing chemical reactions and biological availability assessments.

What kind of earth history is recorded in marine sediments?

The muds that slowly settle to the seafloor are archives that preserve a lot of information about the evolution of the climate and oceans over time. Did you know that marine sediments are like a kind of book that tells us things about the evolution of climate in the past?

How do you explore the ocean on Google Earth?

Using Google Earth Go to the Google Earth Worlds Ocean page. You can use any desktop web browser to see and use Google Earth. Select an underwater area to view. Do this by clicking a thumbnail or zooming into the Earth view to click a pin. Take in the underwater view.

What are the sediments in the marine environment?

Marine sediment refers to deposits of insoluble materials, such as rock, soil particles, and marine organism remains, that accumulate on the ocean floor through various processes like wind, ice, and rivers.

What are the 4 types of marine sediments?

We classify marine sediments by their source. The four main types of sediment are lithogenous, biogenous, hydrogenous and cosmogenous (Table 1 below).
