Study Notes

Aquatic Research - Impact on Societies

Aquatic research is closely related to oceanography and encompasses almost all biological disciplines.
Studying aquatic sciences is important because life on Earth likely originated in water.
Aquatic environments hold immense resources, including those used for medical advancements.
Aquatic plants supply a significant portion of Earth's oxygen.
Coastal ecosystems are essential for human coastal communities.

Reasons to Study Aquatic Sciences

Life originated in water: Life on Earth is believed to have begun in water.
Vast resources: Aquatic environments hold a huge reservoir of resources.
Medical advances: Research on aquatic life has supported many medical advancements.
Essential oxygen: Aquatic plants are vital for producing the oxygen humans breathe.
Coastal communities: Coastal ecosystems support vital human coastal communities.

History of Aquatic Exploration

Ancient Egyptians: Early forms of aquatic commerce began with the Egyptians.
Cretans and Phoenicians (Greeks): These groups developed maritime supremacy in the Mediterranean basin and explored further afield.
First Ocean studies: Researchers at the Library of Alexandria in Egypt laid the groundwork for marine science.
Ancient Chinese: The Chinese conducted early ocean expeditions nearly 600 years ago.
1500s-1800s: European explorers like Prince Henry, Columbus, Magellan, and James Cook undertook extensive expeditions and map making.
1947 (Kon-Tiki expedition): The Kon-Tiki expedition travelled across the Pacific Ocean by raft.
James Cook: He created detailed maps of Newfoundland, discovered New Zealand and Hawaii.
1872 (HMS Challenger expedition): The Challenger expedition, organized by the University of Edinburgh, researched the oceans over four years. Collecting specimens and performing soundings.

Modern Aquatic Exploration

Jacques Cousteau: Invented self-contained breathing apparatus for underwater exploration.
Multibeam sonar: Modern technology for mapping the seafloor like medical ultrasound.
Scientific importance: The ocean depths are complex and a lot is still unknown.

Aquatic Research's Impact on Society

"Blue Planet": David Attenborough's work on this program has raised public awareness about marine pollution and prompted action.
Source of food: The ocean provides protein for billions. Close to 90% of world's fisheries are from the ocean.
Source of Medicines: Marine organisms have provided, and continue to provide, a rich source for new drugs and treatments.
Technological applications: Chemicals and materials from marine organisms are used for medicine, agriculture, industry, cosmetics, and food production.
Bio-fuels: Emerging technology exploring algae as a bio-fuel source.
Water scarcity and desalination: Desalinization transforms ocean water into drinking water, vital in some regions. Over 17,000 plants exist globally. Qatar, for example, relies heavily on desalination.

Aquatic Organisms

Microbial world: Vast and complex populations of microorganisms in the world's water. Number of different types likely very high.
Primary producers: Green algae and seagrass.
Invertebrates: Animals without a backbone.
Vertebrates: Aquatic animals with a backbone.
Organisms of the Water: This encompasses microbial life, plants, and animals.
Uncellular primary producers (Algae and plants): Unicellular algae and plants, such as diatoms and dinoflagellates are important primary producers in aquatic environments.
Multicellular primary producers: Seaweeds and seagrasses are key sources of food and habitats in the ocean. These are multicellular organisms.
Diversity in Aquatic Animals: A wide variety of aquatic animals exist.
Classification and Taxonomy: The science of classifying and categorizing organisms.
Phylogeny: Organism classification based on relationships/ancestors.

Aquatic Animal Classifications

Crustaceans: A large group of mostly marine animals with chitinous skeletons.
Molluscs: A large group typically with external or internal shells. Includes bivalves, gastropods, and cephalopods.
Echinoderms: Radially symmetrical marine animals with endoskeletons. Includes starfish, sea urchins, and sea cucumbers.
Aquatic Vertebrates: Aquatic animals with backbones. Include fish, mammals (dolphins, whales, penguins), reptiles, and birds.
