Marine National Monument

Marine National Monument


The Pacific Remote Islands Marine National Monument is a group of unorganized, mostly
unincorporated United States Pacific Island territories in the Central Pacific, managed by the Fish and Wildlife Service of the United States Department of the Interior. Proclaimed a national monument on January 6, 2009 by U.S. President George W. Bush, the monument covers 86,888 square miles (55,428,480 acres), spanning areas to the far south and west of Hawaii, including Kingman Reef, Palmyra Atoll, Howland Island, Baker Island, Jarvis Islands, Johnston Atoll, and Wake Island.
Within the national monument, resource destruction or extraction, waste dumping, and commercial fishing will be prohibited, but research, free passage, and recreation will be allowed. Additionally, NOAA manages three marine sanctuaries in the Pacific Islands Region including the Papahānaumokuākea Marine National Monument, the Hawaiian Islands Humpback Whale National Marine Sanctuary, and the Fagatele Bay National Marine Sanctuary. The sanctuaries provide protection for a multitude of marine species including sea turtles, dolphins, whales, pearl oysters, giant clams, coconut crabs, large groupers, sharks, humphead wrasses, and bumphead parrotfishes. Expansive shallow coral reefs and deep coral forests – with some corals up to 5,000 years old – are found here. These small dots of land in the midst of the ocean are vital nesting habitat for millions of seabirds and resting habitat for migratory shorebirds. Protecting and studying these special ocean areas provides an opportunity to secure the future of our marine resources and to better understand the functioning of our oceans. Ecological knowledge is key to reef management and restoration, and ongoing monitoring and evaluation of the status of reefs are essential components of these efforts. The system of marine sanctuaries and national marine monuments hopes to help manage and preserve these valuable coral reed ecosystems for generations to come

Exploring the reefs of Hawaii

An eternity, perhaps not quite, but that’s my perception of time when thinking back to my Hawaiian excursion in mid-June.  And finishing up a home movie chronicling our adventure, complete with contemporary Island music from the likes IZ for instance, just gets me in the mood for some white sandy beaches and clear salty waters.  So why not share a few things I came across while swimming over the reefs of Maui.

Obviously such a post lends itself infinity as the amount of pictures and video I have is substantial… notice I did not mention anything about quality.  But with that said, using a digital underwater camera is  a goldmine for someone who needs to cull through the blurs to find a few gems. 
Of course I need to start the ball rolling with a Hawaiian green sea turtle.  It is by far my wife’s favorite marine creature and I am always left in awe at the range of colors found on their carapace.  By the way, did you see our Hawaiian green sea turtle video footage?  And even in today’s world of rampant conservation information,  I was left in shock to discover people clamoring to touch and harass this amazing species (And yes members of our party spoke up immediately to inform the culprits and end their activities). I guess that’s why we need to continue spreading the word.

Exploring Oregon's Rocky Reefs

This is part of a series of posts about our Pacific Hotspots expedition. Today's highlights: rockfish, basket stars and hydroids.
Oregon Leg, Day 1
Last night our six Oceana crew slept aboard the R/V Miss Linda, tied to the dock at the Charleston Marina. The captain and his two crew members arrived at dawn, started up the engines and walked our tired souls through an important safety briefing. The Miss Linda is a 76-foot research charter vessel that formerly worked these Pacific Ocean waters as a commercial fishing boat. The captain is experienced, confident and will certainly lead us safely through our five-day expedition.
Our objective today was to get situated working aboard the Miss Linda with our Remotely Operated Vehicle (ROV) while exploring a large area of rocky reef just south of Cape Arago. Over the next four days we will use the ROV to capture high definition video footage of some of the most remote and rugged areas off the southern Oregon coast.
By our third dive this afternoon, five miles offshore and over 150 feet down, the Miss Linda crew and Oceana crew were in sync. With each drop of the ROV we saw schools of rockfish hovering over a rich tapestry of seafloor life.
On our last dive, we had the ROV in perfect position to watch large schools of rockfish rise with the current over rocks and boulders covered with hydroids, basket stars (pictured above), sun anemones, corals and sponges. We watched a lingcod guard its domain, chasing off another passing lingcod with a powerful bite, and a scallop that swam across the screen like Pac-Man.
Everything worked well today; tonight we are running south to the Orford Reef with another day of exploration and habitat research ahead.

Great Barrier Reef World

Coral reefs are aragonite structures created by living organisms. Coral reefs are usually found in tropical agriculture, which can have little or no nutrition. High nutrient levels such as waste water from agricultural areas can harm the reef by the rapid growth of algae.

Great Barrier Reef coral reef platform of approximately 3,000 individual and 900 islands, stretching 2,600 km, has been recognized as a world natural heritage. Part reef located in the Coral Sea, off the coast of Queensland in northeast Australia. A large portion of the reef-protected Marine Park Great Barrier Reef.

This is an area of biological diversity, including many species in jeopardy and danger. 30 species of whales, dolphins have been recorded in the Great Barrier Reef, including the Dwarf Minke whale, Indo-Pacific Humpback Dolphins, and Humpback whales. A large population of dugongs live well here. Six species of sea turtle come to the reef to breed, such as Green, Leatherback, Hawksbill, Loggerhead, Flatback and Olive Ridley. Over 200 species of birds (including 40 species of waterbirds) live on the air of the Great Barrier Reef, including the white-bellied sea eagles and red tern.

Red Sea Reef

Red Sea Reef
The Red Sea is one of the most beautiful places in the world to go diving and the holiday resorts along its coast are popular tourist attractions in Egypt. The waters of the Red Sea are renowned for their spectacular visibility and features some of the most exotic seascapes. With its wide expanse of coral formation on the reefs, it is home to thousands of different sea creatures.

Bunaken

Bunaken
Located at the north of the island of Sulawesi in Indonesia, Bunaken is one of Indonesia’s most famous dive and snorkeling areas. The best time for diving in Bunaken is between the months of April and November, although diving is not restricted at any time. Bunaken is part of the Bunaken Marine Park where you can see more than 70% of all fish species that live in the western Pacific ocean. That’s a pretty good deal for a single dive.
