HOW ENDANGERED ARE OUR SEAS
CLIMATE CHANGE
The anomalies of the oceans heat
The ocean has the
greatest thermal storage capacity on earth
The water gets warmer and thus expands,
which contributes to rising sea levels
Consequences of warming
:eight_pointed_black_star:
The ocean temperature rises
:eight_pointed_black_star:
Increasing numbers of coral reefs bleach and die off
:eight_pointed_black_star:
Many Marine creatures change their behaviour
:eight_pointed_black_star:
Invasive species spared out and alter ecosystem
OVERFISHING
Intense levels of fishing
POLLUTION
Five large garbage patches
Plastic accumulation
Microplastics in the food chain
Microplastics
Toxic substances in microplastic
Plastic garbage in the oceans
The biggest oil spills
One litre of oil can contaminate up to 1 M litres of drinking water
Oil damage in organism
Sea birds
Little fish
Plants
Humans
Plankton/fish egg
OCEAN-BASED INDUSTRIES
Energy from the ocean
:eight_pointed_black_star: The most important source of energy worldwide is oil. In the future, it will increasingly come from offshore oil rigs
:eight_pointed_black_star: 30% of oil and natural gas already come from deposits below the ocean floor.
Deepwater drilling is a method of exploring for oil and gas sources
There are multiple fixed position installations that are currently in use:
:eight_pointed_black_star: Fixed platform :eight_pointed_black_star: Jack-up rigs :eight_pointed_black_star: Semisubmersible rids:eight_pointed_black_star: Drillships :eight_pointed_black_star: Tender-assits rigs
Increase in offshore wind energy
Wave and Tides-Energy of the future?
Tidal Turbines
This method works much the
same way as wind turbines
The Pelamis
This method work by creating a multisegment floating tube anchored to the sea floor
Wave and tidal energy harvesting has been around for a few decades
A cruel cacophony
Raw material reserves of the deep sea
Harmful ship emission
The wired ocean
