Human Impact on the Oceans

Presented by: Courtney Martinez


Topics covered

Topics Covered:

  • Acidification

  • Dead Zones

  • Over Fishing

  • The Garbage Patch


Acidification

Acidification

“OA” for short, is the term given to the chemical changes in the ocean as a result of carbon dioxide emissions


Acidification1

Acidification

Hawaii Carbon Dioxide Time-Series

Location of planned OA monitoring and research sites and affiliated NOAA labs


Acidification2

Acidification

How the oceans absorb carbon dioxide is critical for predicting climate change

Acidification4

Acidification

How the oceans store CO2 is critical for understanding the global carbon cycle


Acidification5

Acidification

CO2 uptake is not the same as carbon storage. Anthropogenic CO2 absorbed in one region may be moved by ocean circulation and ultimately stored in a different region.

Acidification

In 2008, Oyster harvest plummets 80%

The Road to Remedy?

The IOOS Buoy


Topics covered1

Dead zones

Dead Zones

What causes a dead zone?

Where are they located?


Topics covered2

Topics Covered:

  • Acidification

  • Dead Zones

  • Over Fishing

  • The Garbage Patch


Over fishing

Over Fishing

Fleets = 2-3 Times

bigger than necessary

52% of Fish stocks

are “fully exploited”


Topics covered3

Topics Covered:

  • Acidification

  • Dead Zones

  • The Garbage Patch


The garbage patch

The Garbage Patch

What is it made of?


The garbage patch1

The Garbage Patch

How is it formed?

What’s the problem?
