A new genus (Mesobius), and three new bathypelagic species of Macrouridae (Pisces, Gadiformes) from the Pacific Ocean. [Carl L Hubbs; Tomio Iwamoto]. With little data on the diet of pelagic nemerteans, apreliminary immunoassay survey of the gut contents ofthree species from the Pacific Ocean was performedusing non-specific, cross-reacting.
Pelagic polystiliferous nemerteans, often referred to as Pelagica, represent one of the most enigmatic groups of nemerteans. The group includes 98 valid species assorted into 41 genera and 3–11 families, depending on the classification.
Pelagica inhabit the water column of the world oceans, occupying depths from several hundred to several thousand meters.

Nemerteans of the Pacific Coast of North America, Vol. 1 (Classic Reprint) Posted on Identification of planktonic nemertean larvae from the. Nemertea use organs called protonephridia to excrete soluble waste products, especially nitrogenous by-products of cellular metabolism.
In nemertean protonephridia, flame cells which filter out the wastes are embedded in the front part of the two lateral fluid vessels. The flame cells remove the wastes into two collecting ducts, one on either side, and each duct has one or more nephridiopores. The dashed grey line represents the subduction of the Pacific Plate (to the right) beneath the Philippine Plate (to the left).
The deepest parts of the ocean are within the subduction trenches, and the deepest of these is the Marianas Trench in the southwestern Pacific (near Guam) at 11, metres (Figure ). Viruses are a key component of marine ecosystems, but the assessment of their global role in regulating microbial communities and the flux of carbon is precluded by a paucity of data, particularly in the deep ocean.
We assessed patterns in viral abundance and production and the role of viral lysis as a driver of prokaryote mortality, from surface to bathypelagic layers, across the tropical and. Pacific Ocean - Pacific Ocean - Deep-sea minerals: Metal-bearing deposits on the deep-sea floor, consisting of nodules, crusts, and accumulations of metallic sulfides from deep vents, are of potential economic interest.
In the s and ’80s it was hoped that mining the nodules—which contain quantities of manganese, iron, copper, nickel, titanium, and cobalt, as well as small traces of. Introduction  The growing database obtained with deep‐sea sediment traps tethered to the seafloor [Honjo, ; Lampitt and Antia, ] is providing an increasingly precise understanding of the factors that control particle flux to the ocean c carbon is one of the constituents of settling particles that has attracted much interest, because of its role in sequestering.
The Pacific Ocean is the largest of the Earth's oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south and is bounded by Asia and Australia in the west and the Americas in the east. At million square kilometers ( million square miles) in area, this largest division of the World Ocean – and.
Bathypelagic zone (1,m) - This is a dark zone where water pressure is high and the water is cold (around degrees). Abyssopelagic zone (4,m) - This is the zone past the continental slope - the deep water just over the ocean bottom. This is. Fresh DOC delivered by POC leaving the surface ocean has a modern Δ 14 C value > +50‰, whereas DIC in the mesopelagic zone has prebomb Δ 14 C values and is depleted in 14 C because of radioactive decay (≈− to −‰).
The bulk DOC pool is the “oldest,” with an average Δ 14 C value of −‰ in the deep North Pacific Ocean. An illustration of an open book.

It is from m (19, ft) below sea level to the bottom of the ocean. A trench is a narrow, elongate, v-shaped cavity in the ocean floor. Trenches are the deepest parts of the earth and ocean. Planktonic Crenarchaea are thought to play a key role in chemolithotrophic ammonia oxidation, a critical step of the marine nitrogen (N) cycle.
In this study, we examined the spatial distributions of ammonia-oxidizing Crenarchaea across a large (∼ km) region of the central Pacific Ocean. Examination of crenarchaeal 16S rRNA, ammonia monooxygenase subunit A (amoA) genes, and amoA. Most of the ocean is dark. Yet it is in this darkness, away from photosynthesizing sunlight, that most planetary carbon cycling occurs.
Pachiadaki et al. show that nitrite-oxidizing bacteria in one phylum are the predominant fixers of dissolved inorganic carbon in the mesopelagic ocean. The authors sequenced thousands of single amplified genomes of marine prokaryotes.
Bloop is the name given to an ultra-low-frequency and extremely powerful underwater sound detected by the U.S. National Oceanic and Atmospheric Administration (NOAA) in The sound is consistent with the noises generated by icequakes in large icebergs, or large icebergs scraping the ocean floor.
Analysis. The sound's source was roughly triangulated to a remote point in the south Pacific. The explorers had ventured into the largest ocean on Earth. Covering approximately 59 million square miles and containing more than half of the free water on Earth, the Pacific is by far the largest of the world's ocean basins.
All of the world's continents could fit into the Pacific basin. The Pacific Ocean is the largest and deepest ocean in the world. Asia and Australia border it to the west, with North and South America bordering it on the east. The Pacific Ocean is o, square miles in area, and covers nearly half (46%) of the Earth’s water surface, and about a third of its total surface area.
ABSTRACT: Respiration (= oxygen consumption) rates and electron transport system (ETS) enzyme activities in conjunction with body carbon and nitrogen composition (for respiration) or protein (for ETS) were determined for over 50 copepod species from the mesopelagic (M; to m), upper-bathypelagic (UB; to m) and lower-bathypelagic (LB; to m) zones of the.
Pacific Ocean Facts: Atolls are coral islands in the ocean which are surrounded by a lagoon. Most of the world’s atolls are situated in the Pacific ocean. As atolls are only found in warm ocean water, the southern most atoll are the Coral Sea Islands to the West of the Barrier Reef in Australia.
Below you can see a lagoon in Fiji. Pacific Ocean - Pacific Ocean - Study and exploration: The Pacific Islands are thought to have been peopled by influxes from both mainland and archipelagic Southeast Asia.
The earliest migrations were to what is now generally referred to as Melanesia. From there generations of voyagers ranged northward into eastern Micronesia and eastward into Polynesia.
The Pacific Ocean is the world's largest ocean, covering million square miles of area. The Pacific Ocean accounts for approximately 46% of the earth's water surface area. The last ocean that the Europeans discovered was the Pacific Ocean. A Spanish explorer named Balboa is believed to be the first European to discover the Pacific Ocean, on September 25th, tural history of the islands of the Pacific will welcome the appearance of the first part of a detailed study of the vegetation of a large part of French Oceania by H.

Oceanographers divide the ocean into a pelagic zone, the open water column, equivalent to the sky, and the benthic zone, the ocean floor, equivalent to the c animals are animals that swim or float in the open water, while benthic animals are animals that crawl on the sea floor or are sessile, held to the ocean floor by attachments or burrows.
Economy. Overview: The Pacific Ocean is a major contributor to the world economy and particularly to those nations its waters directly touch. It provides low-cost sea transportation between East and West, extensive fishing grounds, offshore oil and gas fields, minerals.
The Great Pacific Garbage Patch is now 2, times the size of NYC and growing rapidly. – Source There is no Decemin the history of the Pacific Ocean islands of Samoa and Tokelau as the day was skipped when these islands moved their time zone from the last time zone east of the international date line to the first west of the dateline.
The Pacific Ocean is the largest and deepest ocean on Earth. It spans 60 million square miles from California to China, and in certain regions extends tens of thousands of feet below the surface.PACIFIC OCEAN INTRODUCTION AN INTRODUCTION TO THE PACIFIC OCEAN The vast blue depths of the Pacific Ocean await you!
The Pacific is the planet’s largest ocean, occupying over one third of Earth’s surface. The Pacific has been both a barrier and a highway throughout human history.
It contains the deepest place on earth – the Mariana Trench.
