Hello and welcome to our oceanography field trip! Within this trip we will be visiting four
prominent and noteworthy locations that each offer a unique oceanographic feature. Our
first stop is located in Santorini Greece. The red beach is located in area of the island
that was created from erosion from the sliding sediment from the rock surrounding it. As
you gaze upon this wondrous sight, it is evident that the beach received its name from the
red colored nature of the rocks that oversee the beach. The rocks and beach are red in
color due to volcanic rock from the headlands of the beach. The next stop on our tour is
the great blue hole located 60 miles off of the coast of Belize. The hole is approximately
1000 feet across and over400 feet deep. The hole is located within the Lighthouse Reef
which is an atoll off of the mainland shore of Belize. The blue hole began as a
limestone cave that eventually collapsed due to erosion leaving behind what is known as
the blue hole. The blue hole is one of the top ten diving sites in the world. The third
stop on our tour is the Molokini crater located in Hawaii between the islands of Maui and
Kaho'olawe. Molokini is the remains of a giant cinder cone that had a violent eruption about
230,000 years ago it's practically a submerged volcano. This location is excellent for scuba
diving and snorkeling due to its crystal clear waters and offers visibility to depths up
to 150 feet. The last and final stop on our tour are the Galapagos hydrothermal vents.
Hydrothermal Vents are underwater spreading ridges and convergent plate boundaries that
produce hot springs. They are immense chimney like structures. These venting black smokers
release particle-laden fluid composed of mainly fine grained sulfide minerals that is dark
in color. Black smokers are formed from deposits of iron sulfide while white smokers are formed
from deposits of barium, calcium, and silicon. That concludes our tour we hope you enjoyed.
