Scope And Significance Of Oceanography And Marine Biology

What are the Branches of Biology?

The ocean covers more than 70% of the earths surface and contains 99% of the living space on our planet. So, it is important to understand the oceans better for preserving and protecting this complex ecosystem.

Scope of oceanography and marine biology are majorly in,

  • Information from exploration studies is important to find new ocean resources, management, and conservation.
  • Oceans produce more oxygen approximately 70% than the Amazon. Through oceanographic studies, we can establish the baseline information needed to better understand environmental change, fill gaps about rains and droughts, and the carbon cycle.
  • Mangrove, Salt Marshes, Seagrass, Beds, and Coral Reefs support a large number of different species that is, the biodiversity of the ocean is high. Marine biological studies play a crucial role in identifying, classifying, and conserving this very same biodiversity.
  • The continental shells and ocean floor are the storehouses of natural resources including gas oil.
  • The oceans are equally important in the economy. Revenue related to the ocean is mainly from food, tourism, shipping, and biomedical products. Hence knowledge gained through scientific studies is vital to respond appropriately in the face of ocean disasters and to save the economy.


Molecular Genetics And Genetic Engineering

An area of biochemistry and molecular biology studies genes, their heritage, and their expression.

Molecularity is dedicated to the study of DNA and RNA mainly. It uses powerful tools and techniques in the study, such as PCR and its variants, mass sequencers, translation, transcription-commercial kits for extracting DNA and RNA, processes in-vitro and in-vivo, restriction enzymes, and DNA ligases, and the mechanisms of basal expression and inducible gene genome.

It also studies the insertion of genes, gene silencing, and the differential expression of genes and their effect.

Thereby overcoming barriers and boundaries between species, the genome of one species can insert itself into another and generate a new species. One of their top goals is to match current regulatory mechanisms and gene expression, that is, to obtain an epigenetic code. It is an essential pillar in all life science disciplines, especially biotechnology.

Other Branches Or Types Of Biology

Taxonomy: Taxonomy discusses the nomenclature, identification, and classification of living organisms.

Anatomy: Anatomy studies the internal structure of organisms that can be seen with eyes after dissection.

Morphology: Morphology deals with the study of the size, external forms, color, shape, relative position, and structure of the different living organs of alive beings.

Cytology: Cytology focuses on the structure and form of cells and also the activities of the nucleus and additional organelles.

Histology: Histology studies the structure and organization of tissues as seen through a light microscope.

Molecular Biology: Molecular biology deals with the study of the structure, nature, function, physicochemical organization, interaction, and synthesis working of bio-molecules. These biomolecules bring about and command different functions of the protoplasm.

Cell Biology: Cell biology discusses the organizational, morphological, physiological, biochemical, pathological, genetic, evolutionary, and developmental aspects of cell and its elements.

Embryology: Embryology studies the fertilization, division, differentiation, and growth of the zygote into an embryo. In other words, it discusses the early development of alive organisms before the achievement of the size and structure of the offspring.

Physiology: Physiology focuses on the normal functions and processes of living beings and their body parts.

Mycology: Mycology scientifically focuses on fungi.

What Are The Various Qualifications Required To Become An Aquatic Veterinarian

Aquatic veterinarians are required to graduate with a Doctor of Veterinary Medicine degree. This is regarded as a rigorous course that will prepare individuals for a particular field of study.

It includes the study of both small and large marine animals. Many programs offer the DVM degree for individuals interested in the field. Furthermore, there is a licensing exam that they have to clear to become a full-time aquatic veterinarian.

What Exactly Do Ocean Engineers Do

Branches of Biology: Freshwater Biology, Marine Biology, Parasitology ...

There are many responsibilities of an ocean engineer, which largely depends on the nature of the job. For example, professionals may be required to develop, design, and analyze the equipment to operate and study ocean resources. In addition, they will have to prepare system layouts along with schematics and detailed drawings of the same.

These individuals also have to perform the inspection of the machinery involved. They have to design and conduct various tests for performance reviews of the equipment.

Moreover, they have to design and look over the installation procedures for the repairing of the apparatus. Solving engineering-based problems is another thing that they are focused on. This involves exploring and harnessing the coastal and offshore resources.

Devices used by oceanographers and marine biologists need to be handled by ocean engineers. By utilizing the principle and knowledge of engineering, they should build instruments that can stand the saltwater and storms.

They must also remain at sea for a long period of time and stand the test of time. The maintenance of these pieces of equipment is also taken care of by an ocean engineer.

Oceanography Vs Marine Biology

Branches of Biology | Neurobiology, Microbiology, Mycology, Marine Biology |

Ocean depths are home to the most complex life forms. Over the centuries, the deep waters also have given birth to myths, legends, and mysteries that are unexplainable by mankind.

Even though the ocean is the heart of the Earth and without it, we cannot survive, we know very little about oceans. Thats where ocean exploration comes into play. Exploring the ocean is not about wandering in hopes of finding answers but a systematic approach of unveiling everything that is classified as alien or unusual. It is also about making new discoveries. For instance, there are an estimated 1 million species of marine life, close to 228,450 of which weve identified, named, and classified.

    What Are The Qualifications Required To Become A Scuba Diver And Underwater Filmmaker

    You need to have a diving certification for scuba diving to become a professional underwater filmmaker. There are divisions of programs offering you many choices of underwater filmmaking. First, there is a certification based on the basic levels, which more rigorous training sessions will follow.

    Essentially, this will help you to prepare for a diverse range of filmmaking projects. You can become a diving master within just three months of learning scuba diving. Furthermore, there has to be proper utilisation of the knowledge gathered in the particular field of specialisation.

    You need to have great skills in photography to go further into the career of being a scuba diver and underwater filmmaker. There will be much deflection of light and distortions due to the aquatic environment.

    One needs to be aware of the harsh conditions within the depths and surface of the water during photography sessions. Its assumed that a skilled underwater photographer can capture ethereal images of aquatic mammals and the environment.

    How Is Marine Biology Studied

    Advances in technology have opened up the ocean to exploration from the shallows to the deep sea. New tools for marine research are being added to the list of tools that have been used for decades such as:

    • Sounding hydrophones, the microphones counterpart, detect and record acoustic signals in the ocean. Sound data can be used to monitor waves, marine mammals, ships, and other ocean activities.
    • Sonar similar to sounding, sonar is used to find large objects in the water and to measure the oceans depth . Sound waves last longer in water than in air, and are therefore useful to detect underwater echoes.
    • Computers sophisticated computer technology is used to collect, process, analyze, and display data from sensors placed in the marine environment to measure temperature, depth, navigation, salinity, and meteorological data. NOAA implemented computer technology aboard its research vessels to standardize the way this data is managed.
