Lord Howe Marine Park
The Lord Howe Marine Park (formerly known as the Lord Howe Commonwealth Marine Reserve) is an Australian marine park located about offshore of New South Wales, near Lord Howe Island. The marine park covers an area of , encompassing the smaller Lord Howe Island Marine Park, and is assigned IUCN category IV. It is one of 8 parks managed under the Temperate East Marine Parks Network. Conservation values Species and habitat *Biologically important areas for protected humpback whales and a number of migratory seabirds. *A major seabird breeding area, with 14 species found on the islands including masked boobies, grey ternlets, red-tailed tropicbirds, black-winged petrels and Kermadec petrels *Key location for black cod *Due to the convergence of warmer northern tropical and cooler southern temperate waters in the area, many species found in the reserve are at the northern or southern extent of their range.

Parks Australia
Director of National Parks is a Commonwealth corporate entity responsible for the management of a portfolio of terrestrial and marine protected areas proclaimed under the ''Environment Protection and Biodiversity Conservation Act 1999'' (''EPBC Act'').

Kermadec Petrel
The Kermadec petrel (''Pterodroma neglecta'') is a species of gadfly petrel in the family Procellariidae. It is 38 cm long with a wingspan of 100 cm. It is polymorphic, with light, dark and intermediate morphs known. It eats squid, fish and other marine creatures. Distribution It breeds in the Pacific Ocean from Lord Howe Island to the Juan Fernández Islands. Rarely is the Kermadec petrel recorded west of Lord Howe Island, where it maintains a small colony of less than 100 individuals on Balls Pyramid. In the past it also bred in some numbers on the main islands, however, this is seen as unlikely today. The Kermadec Islands are the only place in New Zealand where this species breeds, including on the following islands of the archipelago: Nugent, Napier, Meyer, Dayrell, North Chanter, Macauley, Haszard and Cheeseman Islands. Due to predation by cats and rats, it no longer breeds on Raoul Island, where in 1908 it had an estimated population of c. 500,000 individuals. ...

Dropline
A dropline is a commercial fishing rig consisting of a long fishing line set vertically down into the water, with a series of baited hooks attached to the ends of side-branching secondary lines called ''snoods''. Dropline fishing, or droplining, is a specialized angling technique. Droplines may be set either down underwater trenches or just into the open water column. They have a weight at the bottom of the line and are fixed to the water surface at least one float at the top. They are usually not as long as longlines and have fewer hooks. Droplines can be contrasted with trotlines. Whereas a dropline has a series of hooks suspended sideways off a vertical mainline, a trotline has a series of hooks suspended vertically off a horizontal mainline. Conservation impacts A concern for marine conservation is that droplines are able to access areas that are otherwise natural fish refuges, such as deep sea canyons and seamounts.Australia's Sustainable Seafood Guide: Expanded Edi ...

Lord Howe Island Marine Park (Commonwealth Waters)
Lord Howe Island Marine Park (Commonwealth waters) is a former marine protected area managed by the Commonwealth Department of the Environment, protecting the waters surrounding Lord Howe Island. It was adjacent to the 465.45 km2 Lord Howe Island Marine Park managed by the Marine Parks Authority New South Wales. On 8 November 2012, it was replaced by a new protected area Protected areas or conservation areas are locations which receive protection because of their recognized natural or cultural values.

Tasman Front
The Tasman Front is a relatively warm water east-flowing surface current and thermal boundary that separates the Coral Sea to the north and the Tasman Sea to the south. Naming The name was proposed by Denham and Crook in 1976, to describe a thermal front that extends from Australia and New Zealand between the Coral Sea and Tasman Sea. Geography Originating in the edge of the East Australian Current (EAC), the Tasman Front meanders eastward between longitudes 152° E and 164° E and latitudes 31° S and 37° S, then reattaches to the coastline at New Zealand, forming the East Auckland Current. Topography plays a dominant role in establishing the Tasman Front. Data on the Tasman Front shows that the path of the front is influenced in part by the forcing of the flow over the major ridge systems. Meanders observed in the Tasman Front can be driven by meridional flows along ridges such as those observed at the New Caledonia Trough (166° E) and the Norfolk Ridge (167° E). Abyssal c ...

Middleton Reef
Middleton Reef is a coral reef in the Coral Sea. It is separated by a deep oceanic pass some 47 km wide from nearby Elizabeth Reef, forming part of the Lord Howe Rise underwater plateau. It is around 230 km from Lord Howe Island and 555 km from the coast of New South Wales. In 1997 thEnvironment, Sport and Territories Legislation Amendment Bill 1996included the reef in Australia's Coral Sea Islands Territory. It is among the southernmost platform reefs in the world. Despite its relatively high latitude, there is a wide variety of flora and fauna on the reef and in the surrounding waters, due to converging tropical and temperate ocean currents. It is about 8.9 km long by 6.3 km wide. At low tide most of the reef flat is exposed, at high tide only one cay is visible, The Sound, 100 m by 70 m and one metre above sea level.

Elizabeth Reef
Elizabeth Reef, located at , is a coral reef in the Coral Sea. The reef is separated by a deep oceanic pass, some 47 km wide, from nearby Middleton Reef, both of which are part of the underwater plateau known as the Lord Howe Rise. It is around 150 km from Lord Howe Island and 600 km from the New South Wales coast of Australia. ThEnvironment, Sport and Territories Legislation Amendment Act 1997included Elizabeth Reef in Australia's Coral Sea Islands Territory. It is the southernmost coral atoll in the world and one of the southernmost platform reefs in the world. It measures 10.5 km by 6.1 km. Despite the relatively high latitude, a wide variety of flora and fauna exists on the reef and in the surrounding waters due to their location where tropical and temperate ocean currents converge. At low tide most of the reef flat is exposed; at high tide, both a cay and a sand spit are visible. Elizabeth Island, with a diameter of about 50 m, is one metre abo ...

Lord Howe Seamount Chain
The Lord Howe Seamount Chain formed during the Miocene. It features many coral-capped guyots and is one of the two parallel seamount chains alongside the east coast of Australia; the Lord Howe and Tasmantid seamount chains both run north-south through parts of the Coral Sea and Tasman Sea. These chains have longitudes of approximately 159°E and 156°E respectively. Geography The Lord Howe Seamount Chain has been known under a variety of different gazetted names, including the Lord Howe Seamounts, Lord Howe Guyots, Lord Howe Rise Guyots and the Middleton Chain. The Lord Howe Seamount Chain is on the western slope of Lord Howe Rise, a deep-sea elevated plateau which is a submerged part of Zealandia. The Tasmantid and Lord Howe seamount chains are both broadly within the Tasman basin which is the abyssal plain between Lord Howe Rise and the Australian continental shelf. The two chains lie on opposite sides of the Dampier Ridge which is believed to be a submerged continental ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Integrated Marine And Coastal Regionalisation Of Australia
The Integrated Marine and Coastal Regionalisation of Australia (IMCRA), formerly the Interim Marine and Coastal Regionalisation for Australia, is a biogeographic regionalisation of the oceanic waters of Australia's exclusive economic zone (EEZ). As of 2008, the most recent version is IMCRA Version 4.0. IMCRA actually defines two bioregionalisations: a benthic bioregionalisation, based on biogeography of fish together with geophysical data; and a pelagic bioregionalisation, base on oceanographic characteristics. The benthic bioregionalisation incorporates three separate regionalisations: #A regionalisation of the EEZ into provincial bioregions, based on the biogeography of bottom dwelling fishes. In IMCRA 4.0, 41 provincial bioregions, consisting of 24 ''provinces'' and 17 ''transitions''. #A regionalisation of the continental shelf into ''meso-scale regions'' based on biological and physical characters, and the distance from the coast. In IMCRA 4.0 there are 60 meso-scale re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
