Marine conservation , also known as ocean conservation , refers to the study of Marine plants and animal resources and ecosystem functions. It is the protection and preservation of ecosystems in oceans and seas through planned management in order to prevent the exploitation of these resources. Marine conservation is driven by the manifested negative effects being seen in our environment such as species loss , habitat degradation and changes in ecosystem functions  and focuses on limiting human-caused damage to marine ecosystems , restoring damaged marine ecosystems, and preserving vulnerable species and ecosystems of the marine life. Marine conservation is a relatively new discipline which has developed as a response to biological issues such as extinction and marine habitats change. Marine conservationists rely on a combination of scientific principles derived from marine biology , oceanography , and fisheries science , as well as on human factors such as, demand for marine resources and marine law , economics and policy, in order to determine how to best protect and conserve marine species and ecosystems. Marine conservation may be described as a sub-discipline of conservation biology.
And, depending on the direction your windows face, our harsh natural light can often work against the effect. We take a look at two kitchens that went for a similar look but relied on charcoal grey to bring the drama. No matter where you live or the colour of your collar, living space is at an ever-ascending premium.
But, if you're already squeezed for space, you may need to employ a bit of creativity to carve out a niche where you can get business taken care of. Luckily, the way we work today has greatly reduced the need for physical space in the places where we work. For better or for worse, we're getting more work done than ever before — but we're getting it done by using less Painting the walls with a meadow of Resene Clover brought the bushy surroundings of this home indoors.
The original bathroom presented some challenges for Designer Natalie Du Bois. Not only were things looking pretty lacklustre, the frosted windows were obstructing the captivating view of the bush outside and made the room feel closed in and cramped.
If you've found a home you plan to stay in for quite some time, it's a smart idea to make sure it not only meets the needs of today but also the changes that may be on the horizon. Social, economic and age-related changes can greatly impact the way we use our personal spaces and what we need from them to support those transitions In , Becky Lee hit the reset button and became clear about what direction she wanted to take with her personal and professional life.

View all Habitat magazines View all Habitat plus booklets By moving away from the ocean, they adapted to a terrestrial existence while their major competitors the crustaceans stayed in the sea and continued to adapt.
As millions of years passed, insects lost their ability to successfully compete in the ocean while crustaceans have had only limited success in invading land. Dr Lanna Cheng believes that this is the most likely explanation for the abscence of insects in the oceans. As potential evidence, it is noted that the only insects that live on the open ocean, live on its surface.
As such, they never come in contact with the crustaceans living beneath its surface. There are many questions still unanswered about this strange case of the Halobates. How come that they alone of the so many insects managed to adapt to life on the oceans?
Whatever hypothesis is true, though, if any of them are, the Halobates are a really remarkable example of marine life rarely, if ever, to be observed by divers. New Foundland, Canada.

Read so far. Similar losses affect other regions as well, although on a less grand scale than in coastal Louisiana. Coastal zone Coastal waters and adjacent shorelands which are strongly influenced by each other and uses of which have a direct and significant impact on coastal waters. Creation Construction or formation of a habitat of a different type that existed before a site was disturbed or conversion of one habitat form to another. The principal differences between restoration and creation are the condition and status of the habitat acreage rather than the technologies used.
Because the technology is essentially the same, creation is treated as a subset of restoration as an approach to improving marine habitat. Enhancement Improvement of one or more of the values of an existing habitat, usually one that has been degraded or disturbed.
May result in a decline of other values. Improvement General result, if beneficial, of one or a combination of protection, enhancement, restoration, and creation initiatives. Marine habitat Marine and estuarine habitats and contiguous shorelines within the coastal zone.
These areas include marine wetlands such as tidal marshes, emergent wetlands, sea grass beds, kelp forests, and mangrove swamps.
Also included are beaches, shallow inshore and near shore submerged environments, and tidal and intertidal flats. Offshore marine habitat is outside the boundaries of this assessment except for artificial reefs and offshore berms on the continental shelf.
All Marine Habitat Magazine Backissues Downloads Marine habitat management A comprehensive approach to stewardship of marine habitat including protection, enhancement, restoration, creation, and administration. Mitigation Measures taken to reduce adverse impacts. A regulatory approach that, in effect, permits conversion of habitat in return for compensation in the form of enhancement, restoration, or creation of other habitat.
Monitoring The collection of data to aid project planning and design and to enable evaluation of project performance. Partial restoration Return of a degraded or altered natural area as close as possible to its condition prior to disturbance if full restoration is not feasible Box Protection Use of structural and nonstructural means, including regulation, to minimize or prevent harm to existing habitats.
Restoration Return of a degraded or altered natural area or ecosystem to a close approximation of its condition prior to disturbance Box River delta, intense development of shorelines and inland areas, and use and diversion of fresh water within the watershed are causing or contributing to hypersalinity subsidence and erosion problems Bay Institute of San Francisco, ; EPA, ; Josselyn and Buchholz, ; McCreary et al.
Along much of the Atlantic and Gulf Coasts, engineered. In this report, restoration is defined as the return of a marine natural area or ecosystem to a close approximation of its condition prior to disturbance. In restoration, ecological damage to the resource is repaired. Both the structure and the functions of the natural area are improved or recreated. Merely recreating the form without the functions, or the functions in an artificial configuration bearing little resemblance to a natural resource, does not constitute restoration.
The goal is to emulate a natural, functioning, self-regulating system that is integrated with the ecological landscape in which it occurs. In practical application, since ecosystems are the cumulative result of a sequence of climatological and biological events, full ecological restoration is rarely achieved. Therefore, efforts to restore habitat may necessarily consist of various measures to enhance or partially restore natural functions depending on site-specific conditions, habitat improvement objectives, and other factors.
In some cases, the ecological landscape may have been so altered as to preclude a return to a predisturbed condition. In these cases, partial restoration may be feasible, recognizing that all natural functions may not be completely restored and that assisted regulation may be necessary, such as control of water and sediment flows.
Marine ecosystems typically involve dynamic forces including substantial physical energy in the form of currents and waves, local or global changes in relative mean sea level, and sediment streams that can lead to rapid changes in the characteristics of a natural area. Therefore, defining what constitutes a predisturbed condition can be problematic. In such cases, the characteristics of a natural, functioning, self-regulating system that is integrated into its ecological landscape and which emulates nearby undisturbed natural areas is an alternative frame reference.
Although use of dredged material does not constitute restoration, per se, restoration can be accomplished using dredged material in its native environment to achieve general parameters which will aid in natural marsh evolution in those locations where marine sediments would normally form essential substrates for intertidal and emergent wetlands habitat.
Placing marine sediments so as to mimic natural deposition of sediment at sites where conditions otherwise favor restoration would preclude the chemical changes that occur when marine sediments are exposed to air in upland areas or in wetlands above appropriate intertidal elevations.
The rapid placement of suitable dredged material at appropriate locations and elevations in an estuary or delta approximates natural deposition and can be an important, but not exclusive, element of a marine habitat restoration project.
Engineering technologies and structures maintain an increasingly tentative balance with nature in every coastal state.
Throughout the coastal zone, habitat is continually lost to human development; what remains is under constant threat of degradation or further loss EPA, The causes of the decline in marine habitat quality and quantity may be traced to several factors. Protecting finfish and shellfish habitats is a concern, as are sedimentation starvation and excess sedimentation in deltaic and other fragile wetland systems.
Scientific concern has also arisen regarding the effects of beach stabilization measures, whether physical structures or placement of beach-quality sands, on biotic communities for which beaches provide habitat.
Considerations include the fate of biota in the nearshore borrow area, impacts on biota using the changed shoreline, changes in sedimentation patterns and shoreline stability beyond the project boundaries, and project stability.
Sweeping changes in the policies and practices of all parties involved in marine habitat protection and enhancement are needed to arrest and reverse these trends NRC, a. Institutional, political, and sociological factors that have made it difficult to strike a balance among competing objectives for the use of coastal sites include:.
Despite these constraints, engineers working in the coastal zone and using the technologies and practices they develop can contribute to better management of. Where feasible, these capabilities can be put to use for the protection of natural marine habitats before they are degraded or lost or for after-the-fact enhancement or restoration.
It is time to rethink the role of coastal engineering in serving both human and environmental objectives. An integrated, holistic approach that encompasses engineering practices and capabilities and understands the functions of marine ecosystems and their habitat is especially important.
Engineers are faced with seemingly contradictory objectives: Through research and development, education, and the innovative application of engineering knowledge, the engineering profession has the opportunity to accommodate these competing objectives. A comprehensive understanding of engineering practices and capabilities and their relationship to the ecology of marine habitats is as important to informed decision making over habitat use as are economic considerations.
A positive role for the engineering profession can be developed in cooperation with the scientific community to protect and enhance marine habitat and contribute information essential to the formation and refinement of national policy and management objectives.
Although examples of successful applied engineering capabilities to accomplish environmental objectives are numerous, traditional engineering practices have not always recognized and dealt fully with the varied needs of marine habitats.
New territory for the engineering profession includes methods to protect habitats, especially from contaminants, erosion, and subsidence, while preserving or retaining their natural attributes.
An ecosystem approach to project design and implementation that recognizes the ecological interdependencies of marine systems is seldom applied. Further development of the potential for coastal engineering to protect, enhance, restore, and create marine habitats therefore depends in part on further collaboration between the coastal sciences and engineering. Scientists and engineers concerned with marine systems share many interests and have a wide variety of tools at their disposal.
Some technology transfer has occurred, demonstrating the fact that science and engineering can be complementary. For example, marine turtles returned to historical beach nesting areas after well-timed deposition of beach-quality dredged material. Knowledge of habitat requirements, when the turtles came ashore to nest, and the capability to place beach-quality material prior to turtle arrival were required.
Applied research has demonstrated that beach nourishment can be timed to accommodate environmental, stabilization, and aesthetic objectives. This measure is now widely used in Florida Higgins and Fisher, ; Hodgin et al.
Fisheries biologists and navigation project design engineers interested in successful construction and maintenance of navigation channels are both concerned with hydraulic and hydrologic conditions, water quality, sedimentation patterns, salinity and temperature, and other physical and chemical factors. Although discipline perspectives differ, each group is vitally interested in the effects of physical modifications to an existing system.
For example, changes to an estuary's tidal prism that do not maintain hydraulic balance within the system can greatly affect sedimentation rates and salinity, benefiting either navigation, biota, both, or neither. The full potential of scientific and engineering contributions to marine habitat protection, creation, restoration, and enhancement has yet to be realized despite the advances that have been made.
Over the past three decades, the scientific community's understanding of marine habitats has advanced greatly. Science produced monitoring, sampling, and analytical techniques that help detect and respond to problems affecting marine habitats.
