Exploring the Sea Depth at "Deep Heart" Station

Exploring the Sea Depth at "Deep Heart" Station

The first-class deep-sea analysis station placed 50 km (31m) of the Israeli coast referred to as "DeepLev", which combines the "deep" which means of Israel with a coronary heart that’s "lev." A depth of 1.5 km (~ 1m) reaches a new mild for the Japanese Mediterranean Sea setting and the effects of this ecosystem change on people.

The marine setting accounts for greater than 70% of the planet's surface, owns 97% of all water and is a life on earth. Nevertheless, the ecological, physical and chemical processes underlying the marine ecosystems are still largely unknown. These processes present vital benefits to individuals and produce other implications for us; it’s subsequently necessary to have a better understanding of them. First, anchored in January 2017, scientists have invested about three hours of sailing distance from Haifa in northern Israel, the first deep-sea research station (referred to as DeepLev)


”This is unique Initiative in the Japanese Mediterranean, ”says Professors Ilana Berman-Frank and Yishai Weinstein Bar of the University of Ilan, who jointly lead the undertaking Professor Barak Herutin and dr. Timor Katz from Israel for Maritime and Limnological Research (IOLR). The challenge – complicated and resource-efficient – was designed and carried out in collaboration with colleagues from the Hebrew College of Jerusalem, the College of Tel Aviv and the Geological Survey of Israel. Its main goal is to seek out out what is basically occurring on the open sea and the results of human exercise and international change on this setting: “We do it at a station that is anchored in a fixed place that follows and constantly monitors what's happening there,” says Professor Berman-Frank .

The group cannot only monitor processes but in addition perceive their significance and implications for human society: “understanding these processes is very important, because it helps us understand how the whole system works, ”he points out. “An event at one sea location can affect other parts of this area. The eastern Mediterranean is a particularly sensitive environment affected by climate change and other human pressures – gas exploration, maritime transport, industrial and agricultural pollution and desalination plants; data collection is essential to predict potential ecosystem responses to these various pressures. “

Station equipment continuously and independently collects information that allows researchers to study biological activity processes, currents and wave patterns, and deep organic matter flows from the surface. The latter is especially important to understand how the marine environment survives the rise in atmospheric carbon dioxide; it is called professionally a "biological pump." Small sea plants using algae – algae – that are critical in regulating carbon dioxide and sea acidity

Algae are the basic structure of the sea food that is grazed by other Sea creatures While the dead algae sink into the bottom of the sea: “Levi is crucial because they carry extra carbon dioxide from the atmosphere to the sea bottom and help curb global warming,” says Professor Berman-Frank. “Our projects are also designed to better understand carbon and other particles from biological or other sources,” Professor Weinstein provides. "Devices called" sedimentants "are placed along the cable and are captured by particles; we can measure currents and understand the dynamics of sedimentation along the water column gradient to the seabed. "

" An article by IOLR Dr. Tal Ozer, published in April 2016 in Global and Planetary Change, summarizes 30 years of measurements in the eastern Mediterranean and analyzes changes in sea temperature and salinity, "says Professor Barak Herut, IOLR CEO.

”It clearly demonstrates the proof of ocean warming and climate change. The Mediterranean physique is split into several layers. There’s warming in the center layer, which is according to the IPCC (Intergovernmental Panel on Local weather Change) forecasts; nevertheless, the surface layer temperature rises a lot quicker than the prediction. “This phenomenon, according to Herut, is very important because it affects the occurrence of extreme weather events, rainfall and, of course, the ecosystem. The new monitoring station will continue to help track these trends and predict their potential consequences.

Another important part that the research team wants to study is the effect of the change in the surrounding environment (depth of about 200 meters) on the deep sea. Professor Herut explains that "coastal waters have a higher level of pollution due to a wide range of human uses. The monitoring station helps to study the interactions between the two environments. "Preliminary data for the first six months already shows that coastal waters have a greater impact on certain periods of time:" and the position gives us a better chance to measure these interactions and assess their future

The new Israeli position is one of many similar monitoring stations around the world the ocean and one in the northwestern Mediterranean, led by a French organization. According to Professor Herut, "we strive to use these stations in the long term and gain a deep understanding of what is happening in the marine environment."

He emphasizes that data from marine stations exceed the sea itself: "Understanding that the increasing level of atmospheric carbon dioxide is a threat to planetary systems is the result of long-term monitoring of permanent status." The position of Israel also follows the level of carbon dioxide and thus follows the process of acidification of the sea, which affects marine organisms that use calcium carbonate to build their skeletons and shells (eg plankton species, corals, snails or oysters). “The new station and IOLR station work in different locations, are part of an international network to monitor the ocean's acidity levels (pH), and they help us assess whether sea acidification also occurs in our part of the world, and if so, at what speed. ”

The station is a considerably large cable that is 1.5 kilometers lengthy and has several types of measuring units at totally different depth ranges. It has been fastened to a selected location for six months to collect knowledge, so scientists take it off to take measurements and drop it back for an additional six months. "It might appear to be a trivial activity that places a couple of units at a depth of 1500 meters," says Professor Berman Frank, however took his doctoral scholar group led by Dr. Timor Katz and Ronen Alkalay. had to rigorously think about how the station would stay secure, in exactly the similar place we needed to have, accounting for the currents and storms right here, and defending it from ship collisions or unintentional injury. Herutin's reviews are a new government-funded “Bat Galim”, which IOLR has acquired as the most superior research vessel by Levant. and we carried out the activity only at sundown. It is a logistically complicated endeavor. "Professor Herut provides:" the placement or withdrawal of such a status requires really deep sea of ​​info and I'm comfortable to say that we have now successfully reached it. Apart from insurance coverage, mortgages, upkeep, gear, or other conceited days, the direct value of every day at sea exceeds $ 10,000. Station gear can also be very expensive: 1,500 meters of multiple instruments and floating units which have to face up to water strain. Throughout every extraction, the batteries of the devices have to be replaced they usually additionally value hundreds of dollars. To extract the knowledge, the devices have to be dismantled and re-assembled.

”Although it is logistically complicated, this funding pays at the finish of the day as a result of the station can provide knowledge for years and it might not only help educational research but in addition other public and government objectives. This is not just a analysis platform; it supports evidence-based decision-making in numerous fields. “

One such area is economic activity in the Mediterranean. About half a billion people live around the Mediterranean, which means increasing human pressure on the marine environment. “The Israeli shoreline is full of power stations, desalination plants that release chemical pollution, natural gas exploration and production facilities, and their infrastructure,” says Professor Berman Frank. “Industrial, urban and agricultural wastewater are discharged into the sea. All these have an effect on the ecosystem and threaten individuals's well-being. We now know that city and agricultural wastewater saturate the marine setting with nitrogen and phosphorus that result in "algal blooms," some of which are toxic, and this has led to the deaths of cattle, pets and even people around the world.
