vocabulary list
| Word | Definition |
|---|---|
| Plankton | Plankton are microscopic organisms that drift or swim in the ocean, including phytoplankton (plants) and zooplankton (animals). |
| Phytoplankton | Phytoplankton are microscopic, photosynthetic organisms that drift in ocean water, forming the base of the marine food chain. |
| Zooplankton | Zooplankton are small, often microscopic, animal organisms that drift in the ocean, serving as a vital food source for marine life. |
| Marine biology | Marine biology is the scientific study of organisms that live in the ocean, including their behavior, physiology, and ecological interactions. |
| Ocean currents | Ocean currents are continuous, directed movements of ocean water caused by a combination of wind, temperature, salinity, and Earth's rotation. |
| Biogeochemical cycles | Biogeochemical cycles are the pathways through which nutrients are exchanged between living organisms, the atmosphere, and the environment. |
| Primary production | Primary production refers to the process by which organisms, such as phytoplankton, convert sunlight into organic compounds through photosynthesis. |
| Marine ecosystems | Marine ecosystems refer to the interconnected web of organisms and their physical environment in the ocean, including coral reefs and kelp forests. |
| Salinity | Salinity refers to the concentration of dissolved salts in seawater, typically measured in parts per thousand (ppt) or practical salinity units (psu). |
| Nutrients | Nutrients are essential chemicals, such as nitrogen and phosphorus, that marine organisms need for growth and metabolism in ocean ecosystems. |
| Phytoplankton | Phytoplankton are microscopic marine organisms that obtain energy through photosynthesis, playing a crucial role in marine food webs. |
| Dissolved oxygen | Dissolved oxygen refers to the amount of oxygen gas dissolved in seawater, essential for the survival of marine organisms. |
| pH | pH in Chemical Oceanography refers to the measurement of acidity or alkalinity of seawater on a scale of 0-14. |
| Trace metals | Trace metals in Chemical Oceanography refer to metals present in seawater at very low concentrations, typically below 1 µg/L. |
| Carbon cycle | The carbon cycle in chemical oceanography involves the exchange of carbon dioxide between the atmosphere, ocean, and marine organisms. |
| Thermohaline circulation | Thermohaline circulation refers to the large-scale movement of ocean water driven by differences in temperature and salinity. |
| Ekman transport | Ekman transport refers to the net movement of surface water in the ocean caused by wind stress acting on the water. |
| Upwelling | Upwelling is the phenomenon in which cold, nutrient-rich water from the deep ocean rises to the surface, supporting marine life. |
| Sea surface temperature | Sea surface temperature refers to the temperature of the top layer of the ocean, typically measured using satellites or buoys. |
| Ocean currents | Ocean currents are continuous movements of seawater driven by various factors such as winds, temperature, and salinity gradients. |
| Salinity | Salinity refers to the concentration of dissolved salts in seawater, measured in parts per thousand, influencing the water's density. |
| Density | Density in physical oceanography refers to the mass of seawater per unit volume, affected by temperature, salinity, and pressure. |
| Coriolis effect | The Coriolis effect is the deflection of moving objects, such as ocean currents, due to the Earth's rotation. |
| Seafloor | The seafloor refers to the bottom of the ocean, which includes various geological features such as ridges, trenches, and abyssal plains. |
| Plate tectonics | Plate tectonics is the scientific theory that Earth's lithosphere is divided into rigid plates that move and interact with each other. |
| Submarine volcanoes | Submarine volcanoes are underwater vents or fissures in the Earth's crust where molten rock and gases are discharged. |
| Sedimentation | Sedimentation is the process of particles settling to the bottom of a body of water, often forming layers over time. |
| Seamounts | Seamounts are underwater mountains that rise from the ocean floor but do not reach the water's surface. |
| Mid-ocean ridges | Mid-ocean ridges are underwater mountain ranges where tectonic plates are moving apart, allowing magma to rise and create new oceanic crust. |
| Continental shelf | The continental shelf is the shallow, submerged extension of a continent, typically extending from the shoreline to the continental slope. |
| Oceanic crust | Oceanic crust is the outermost layer of Earth's oceanic lithosphere, composed mainly of basaltic rock formed at mid-ocean ridges. |
| biodiversity | Biodiversity in marine ecology refers to the variety of species and ecosystems present in the ocean environment. |
| ecosystem | An ecosystem in marine ecology refers to a community of organisms interacting with each other and their physical environment. |
| coral reef | A coral reef is a diverse underwater ecosystem formed by the accumulation of coral skeletons and inhabited by various marine species. |
| plankton | Plankton are small organisms that drift or swim in the ocean, serving as a crucial food source for many marine animals. |
| marine conservation | Marine conservation refers to the protection and preservation of marine ecosystems, species, and habitats to ensure their long-term sustainability. |
| ocean acidification | Ocean acidification is the ongoing decrease in the pH levels of the Earth's oceans caused by the absorption of carbon dioxide from the atmosphere. |
| marine protected areas | Marine protected areas are designated oceanic zones where human activities are restricted to conserve marine ecosystems and biodiversity. |
| coral reefs | Coral reefs are diverse underwater ecosystems formed by colonies of tiny animals called corals, providing habitat for numerous marine species. |
| overfishing | Overfishing is the practice of catching fish at a rate faster than they can reproduce, leading to depletion of fish stocks. |
| marine pollution | Marine pollution refers to the introduction of harmful substances into the ocean, damaging marine ecosystems and endangering marine life. |
| sustainable fishing | Sustainable fishing refers to fishing practices that ensure the long-term health and viability of fish populations and marine ecosystems. |
| marine biodiversity | Marine biodiversity refers to the variety of life forms within marine ecosystems, including species, genetic diversity, and habitats. |
| marine ecosystems | Marine ecosystems refer to the interconnected marine organisms and their physical environment, including coral reefs, seagrass beds, and open ocean habitats. |
| marine conservation efforts | Marine conservation efforts refer to actions taken to protect and preserve marine ecosystems and species from human impact and degradation. |
