Deep Sea Deep Secrets

A hydrothermal vent is a place in earth's surface where geothermally heated water comes out. They are common around places where tectonic plates are moving apart from one another. Under the sea, these vents might form features called black smokers.

Holger Jannasch worked for Wood Hole Oceanographic Institution and helped study the deep sea. He along with his institution were the first to study the deep ocean floor. They were able to bring samples back from the ocean floor that allowed them to study the species.

Alvin was the submarine used by the institution to gain access to the ocean floor. It was the first of its kind and had a robotic arm that allowed for gathering of specimens on the floor. This allowed for new information to be obtained that could not be seen before.

Tube worms were one organism that lived on the ocean floor. They are worm like invertebrates that anchors its tail to an underwater surface and secretes around its body a mineral tube, into which it can withdraw its entire body.

Topographical and Digitizing Maps

We were assigned to pick a geographical spot and place three elevation lines on the spot. The red line represents an elevation of 900 ft. The yellow line represents an elevation of 1200 ft and the blue line represents an elevation of 1500 ft. This is just the basics of  Topographics where people inspect different land plots.

Cemetary Demographics

     We recently went to Riverside Cemetery where we looked at the age of people that died in 1918 during the Spanish Flue pandemic and also the age of people that died between 1960-1980. The goal was to see if there was any differences of lifespan of people in the two time periods. After looking at the data that we pulled, people that died in 1918 had a shorter life span compared to those that died between 1960-1980. Below is the data:
