Answer (1 of 4): I'm going to assume you mean the three zones of the Ocean based on light levels, so hopefully this answer helps. There is less pressure in this zone than in other parts of the ocean. Below the euphotic zone is the dysphotic zone, which can reach from 200 to as deep as 1,000 meters (656 to 3,280 feet) below the surface. 1. This layer is also known as Euphotic Zone/Sunlit Zone. . Using the results of the analysis, we create global seasonal maps of predicted particulate Cd:P distributions. The water in the disphotic zone is cold (the temperature ranges from 41 to 39 degrees F) and decreases with depth. These observations of a bacterial bloom in such cold water provoke questions about the role of temperature regulation of bacterial dynamics, which cannot be addressed in a review of this scope. Although the larvae can develop on a diet of unicellular algae, they cannot tolerate temperatures in the euphotic Zone where this food occurs. …the ocean, is called the aphotic zone. . From this stand point the oceans are vertically divided into two zones: (1) Photic or euphotic zone represents the upper surface up to the depth of 200m and receives solar radiation. Download Download PDF. Thermocline. For example, high nutrient levels will encourage a greater biomass of phytoplankton near the surface, which causes shading and consequent reduction in depth of the euphotic zone. (1 . (AS 1) Answer: In deeper lakes during summer only the surface water is heated up while the deeper layer remain cold.

The bathyal zone, extending from 200 m (656 ft) to 2,000 m (6,562 ft); abyssal zone, extending from 2,000 m . Additionally, the euphotic zone is influenced by temperature, supraoptimal light levels, nutrient limitations, nonhomogenous distribution of phytoplankton biomass, or even compositional changes of the assemblage within the water column. The increase in temperature and decrease in the amplitude of seasonal mixing through the 2010s was correlated with a . The euphotic zone (i.e., the "producing" region) consists of the waters into which sunlight penetrates, and extends down about 180 m below die surface. . Introduction [2] Euphotic zone depth, z 1%, reflects the depth where only 1% of the surface photosynthetic available radiation (PAR) remains [Kirk, 1994]. Approximately 1 week later (16 July 2012), temperatures in the lower euphotic zone had warmed and N+N concentrations had decreased, reflecting the relaxation of isopycnal surfaces that had previously been displaced upward with consumption of N+N along those surfaces. The depth of the euphoric zone ranges from 200 meters (660 feet) below the surface to 800 meters (2640 feet) deep. It begins at a depth of anywhere between 200 m (660 ft) to 1,000 m (3,300 ft), and extends all the way down to the ocean floor. The upper layer of the ocean is known as the sunlit, or euphotic, zone.
