Pan and zoom within the map area until you have highlighted a small region along the
Pacific Coast of the United States. Use the snapshot feature to record below the region of study.

Use the legend to identify the common name of deep-sea sponges in the region you selected.
Note: For additional information on each species, select an icon to open a pop-up box.
Explore the biodiversity in the region. What are the three main species of sponges in the region?
glass sponge, demosponge, Unspecified, (Coast of California) Click the Layer
tool at the bottom-right corner of the map.
Note: To toggle the visibility of each layer, select the eye icon to the left of the “Seafloor Salinity (pss)” and “Seafloor Dissolved Oxygen (ml/l)” layers.
Describe the level of dissolved oxygen and the average seafloor salinity level in your region of study.
Sea floor dissolved oxygen is 4.1ml/l and the Seafloor salinity is 34.7 g/kg. On the Seafloor:
How do dissolved oxygen and salinity levels impact the biodiversity of deep-sea sponges and corals?
“Changes in temperature and dissolved oxygen that go beyond what the
deep-sea corals and sponges are used to could stress the species' physiology affecting growth, tissue loss and reproduction.”

Record the species name and location information for each sponge class sample you are harvesting.
Glass Sponge: Blake Plateau, Atlantic Ocean, Florida Coast
Demosponge: Blake Plateau, Atlantic Ocean, Florida Coast Sponge Unspecified: Blake Plateau, Atlantic Ocean, Florida Coast
Insert screenshots below of the pop-up boxes for each sample to verify each criterion has been met.
Write one to two paragraphs to justify your sample selection.
The reason I chose these sponges was because they were the only ones that I had access to in Blake Plateau.
