Threats to Ecosystem: Cause and Solution
There are various threats to the marine ecosystem. Three of the most common are:
(a) Pollution from point and nonpoint sources; (b) Overexploitation of marine stocks that can deplete marine animals; and (c) Continue Reading...

Comparing Approaches to the Carbon-Based Productivity Model: Assessing the Sensitivity of Remote Sensing-Derived Phytoplankton Productivity to Mixed Layer Depth.
The purpose of this review is to compare approaches or variations of appr Continue Reading...
It is difficult to assess to what extent these changes be contributed to global warming, however, due to the relatively short history of observation available to oceanographers. The events put forth in the Pentagon Report are a plausible scenario, a Continue Reading...
endangered coral reef ecosystem. Coral reefs, when they are healthy, are one of the most diverse ecosystems on the planet. They contain so much life and interaction many scientists call them the "rainforests of the seas." Yet these reefs are endange Continue Reading...
Coral reefs are often coined as the rainforests of the sea, and they are one of the most diverse ecosystems on the planet. Although they cover less than 1 percent of the Earth's surface, coral reefs house about one-third of all marine species. It Continue Reading...
Human Effects on Coral Reefs
Coral reefs are one of the oldest ecosystems in the world, existing for more than 450 million years.
A coral reef is a type of biotic reef that develops in tropical waters. Coral reefs are found in all oceans of the wor Continue Reading...
The fact is that numerous rooted macrophyte structures are not full of naturally strong and healthy particles and sediments and nutrients. It is because of the restriction or absence of these particles, sediments and nutrients that the study of the Continue Reading...
Speed here is of essence and spices like flying fish are able to jump out of water to escape predators. Others that lack like jellies are transparent. Turtles will have a shell to protect them. Gills enable animals to manage different water pressure Continue Reading...
The Delta is also a habitat for many species of fish, birds, mammals, and plants, and it supports agricultural and recreational activities while also being the focal point for water distribution throughout the State.

Barrier island beaches generally develop where:
a The coast is composed of hard rock b the nearby land has a rugged topography of hills and mountains c the sea floor deepens rapidly offshore d The sea floor remains shallow for a long dist Continue Reading...
" Because of the ability to reproduce in large amounts in a small amount of time, phytoplankton are considered as the first link in the food chain of nearly all marine animals. Phytoplankton provide food for a large variety of organisms, including th Continue Reading...
" (SD, 1)
McClintock goes on to connect this to pointedly negative consequences for marine life, arguing that many invertebrates are distinctly vulnerable because their protective shells require many of the nutrients naturally available in their sur Continue Reading...
Yet, there have been transplant successes in sheltered embayments. One of the major conclusions that have been seen is that the cost of reef repair and coral transplantation is generally high but effectiveness is usually very low. Protection and con Continue Reading...
" Beyond that, another 26,000 tons of "plastic packaging material" is dumped by the fishing industry each year, Sverdrup's text maintains. Why is plastic trash so bad? First, there are over 50 million tons of plastics produced in the U.S. annually, a Continue Reading...
Pollutants Compound Threats to Coral Reefs and What That Means for the Ocean and Us Humans
POLLUTANTS AND CORAL REEFS
All over the world, the existence of coral reefs in the oceans face a lot of danger caused by pollutant compounds. A lot of consi Continue Reading...
S. has jurisdiction. The dumping specifically of biodegradable plastics into the sea in these navigable waters and in offshore areas less than 25 nautical miles from the nearest land is strictly forbidden. Metals, bottles, crockery and similar garbag Continue Reading...
Remote sensing can be utilized in order to give succinct information regarding the arrangement and the constituents of coral reef materials. The biological and physical attributes of the water bodies in which the coral reefs exist are monitored over Continue Reading...

Rachel Carson was a scientist and author who took a topic which had hitherto been only of interest to fellow scientists and opened it up to the masses. During her lifetime, she took up many causes in support of wildlife and the protec Continue Reading...
As the eel gets closer to the ocean, the water of course becomes salty and there are new dangers (fishing nets) and unfamiliar eels in the water. But true to her style of providing readers with sidebar stories, the eel passes a clay cliff where "th Continue Reading...

Hamilton explains that while Continental Lithosphere is as much as 93 miles thick, the "Oceanic Lithosphere" is much thinner - up to perhaps six miles. Indeed, the oceanic crust makes up only 0.099% of earth's mass, according to Hamilton. Oceanic Continue Reading...
The contribution of these discoveries to the field is significant. It could for example contribute to a greater understanding of the origin of life on earth. Scientists for example can further study the creatures discovered around the vents for the Continue Reading...

Sea grass is a type of vegetation that grows on the sea floor and is only consumed by sea turtles (Green Turtles especially) and manatees. It must permanently be "cut" short in order to remain healthy, and beds of sea grass are vital breeding and de Continue Reading...

Dredging refers to the activity needed to be conducted for removal of unwanted deposits present in water pathways. However, even though this activity facilitates marine traffic regularity, it isn't without its drawbacks[fo Continue Reading...
This will help them to live and address their short-term challenges. At the same time, there will be a retraining and jobs creation program for these individuals. This will ensure that they are able to quickly transition into new careers to support Continue Reading...
It should not be a difficult question to answer: we must begin reducing ocean pollution and taking steps to prohibit overfishing of our ocean shallows.
The plan that is formulated to address the overfishing and man-made pollutants in the coral reef Continue Reading...
Negative Effects of Artificial Reefs
Artificial reefs are man-made habitats that are created from many different materials to build new marine life communities (Rodriguez, 2004). For many years, fish and shellfish habitats have been damaged or wipe Continue Reading...
Coral reefs [...] their status, purpose, and benefit to the environment. Coral reefs serve a vital purpose in the ocean's ecological balance. Reefs provide substantial benefits to the ocean's ecosystem, to their populations, and to man. They provide Continue Reading...

Sea turtles do not appear to possess features necessary for a similar mechanism, and yet they are able to find their way to favored spawning locations even when placed in unfamiliar parts of the ocean hundreds of miles from their target (Luschi et a Continue Reading...
Just as the physical properties of ocean water and lake water differ from one another in some ways but relatively similar in others, that is also the case with much of the biological life in the respective environments. On one hand, many freshwater Continue Reading...
