<p>in Indonesia is a region bordering the sea region of Indonesia determined by the law which included sea bed, land under it and water above it with the limit of 200miles. This is measured from Indonesian line of the sea.This whole time a lot of people see the shoreline as the sea border. This perspective makes us alienated and lack of knowledge to take advantage of the sea. This understanding also conjures the idea sea toll, to confirm that Indonesia is maritime country. Sea toll means building sea transportation with ships or sea logistic system which will serve nonstop back and forth from Sabang to Merauke. One of the factors to support this is by building ports (deep sea port) order to give faraway to big ships. A course that spreading as far as 5,000 kilometers or an eighth circumference of the earth One of the purposes of sea toll is to move the economy as efficient and evenly as possible. With the hope that, there will be ships back and forth on Indonesian water, so logistics cost will be cheap. That is why; sea toll is one of President Joko Widodo’s priorities which are also meant to develop Indonesia as maritime country and develop Indonesia as national unity. In addition sea toll can also be affirmation, that Indonesia is in every regions even if it is through ships.</p><p><strong>Keywords : Exclusive Economic Zone (ZEE) , Sea Toll , The Shaft Maritime, A Seaport</strong></p>

AbstractHeterotrophic protists (unicellular eukaryotes) form a major link from bacteria and algae to higher trophic levels in the sunlit ocean. Their role on the deep seafloor, however, is only fragmentarily understood, despite their potential key function for global carbon cycling. Using the approach of combined DNA metabarcoding and cultivation-based surveys of 11 deep-sea regions, we show that protist communities, mostly overlooked in current deep-sea foodweb models, are highly specific, locally diverse and have little overlap to pelagic communities. Besides traditionally considered foraminiferans, tiny protists including diplonemids, kinetoplastids and ciliates were genetically highly diverse considerably exceeding the diversity of metazoans. Deep-sea protists, including many parasitic species, represent thus one of the most diverse biodiversity compartments of the Earth system, forming an essential link to metazoans.

Norse Mythology

This chapter presents a case study of one myth that we have from pictorial sources in the Viking Age, from poems almost certainly composed in the Viking Age, and from thirteenth-century sources, namely the encounter between the god Þórr (Thor) and his cosmic enemy, the World serpent, a beast that encircles the earth, in the deep sea. In this myth, Þórr fishes up the serpent, and depending on the variant, Þórr may or may not kill the serpent. I present and analyze the texts in more or less chronological order, from the older skalds through the Eddic poem Hymiskviða, through Snorri Sturluson in Edda, and compare the texts to the rock carvings that portray the myth. I argue that the issue of the death or survival of the serpent is less important than the simple fact that Þórr had the serpent on his hook.

Radiolarian Assemblages

In the equatorial Pacific, between the Galapagos Islands and the coast of South America, two kinds of upwelling of oceanic waters occur. One is related to coastal upwelling and the other to surfacing of the Equatorial Undercurrent. Both of those processes are associated with the development of the southeast trade winds blowing in this area. Coastal upwelling is increased when the trade winds are intensified, and the surfacing of the Equatorial Undercurrent occurs when the trades weaken. The development of coastal upwelling and the surfacing of the Equatorial Undercurrent are inferred from the radiolarian assemblages in the sediments. The abundance of quartz, opal, and radiolarian assemblages in the deep-sea sediments of this area, as well as the distance from the sample locations to land and to the quartz source, is correlated with the intensity of the trade winds (in February and August) through multiple regression analysis. The chronostratigraphy of core V19-29 (3°35′S, 83°56′W), used in this study, is inferred on basis of its δ180 record. During the last 75,000 years, the fluctuations in intensity of the trade winds have been concurrent with or preceded the fluctuations in the amount of ice stored on the continents. In general, the wind velocity of the winter trades has been intensified during cool climatic stages of the earth (δ180 stages 4 and 2) and they have been relaxed during warm stages (δ180 stages 3 and 1). Seasonal contrast of the trade winds has also fluctuated within time, having been relatively high during the upper part of δ180 stage 3.

The sea is unquestionably the most powerful dynamic agent on the surface of the globe, and its effects are deeply imprinted on the external crust of our planet; but among the sedimentary deposits which are attributed to its action, and among the effects which it has wrought on the surface features of the earth, the attention of geologists has, till within quite recent times, been principally directed to the phenomena which take place in the immediate vicinity of the land. It is incontestable that the action of the sea along coasts and in shallow water has played the largest part in the formation and accumulation of those marine sediments which, so far as we can observe, form the principal strata of the solid crust of the globe; and it has been from an attentive study of the phenomena which take place along the shores of modern seas that we have been able to reconstruct in some degree the conditions under which the marine deposits of ancient times were laid down.

Theoretical Developments

Based on the data of theoretical developments in the fields of ocean geography and system-geographical analysis, a hierarchical scheme of natural systems in the water layer of the World Ocean has been examined. The aim of the work is to carry out the first attempt to compare landscapes on land, natural systems in the coastal zone (the zone of contact between land and the World Ocean) and those in the World Ocean. The differentiation of the oceanic natural environment which is a possible version of a systematised list of systems ranging from individual oceans to individual eddies (or impulses) in the deep sea and on the shelf of shallow water are discussed. This work therefore, attempts to find new ways for the synchronous study of the hierarchical series of the coastal zone and the water layer of the World Ocean, along with land landscapes as part of the geographic shell of the Earth. This approach will make it possible to obtain a series of systems for the entire geographic envelope. This is a promising approach for an indebt development of physical geography in general.
