Reefs of deep-sea corals are discovered for the first time in the Mediterranean, offshore of Israel, by the Nautilus cruise

04.10.2010
*"It's like finding a flourishing oasis in the middle of the desert," said Dr. Yizhaq Makovsky, who directed the University of Haifa control center for the Nautilus expedition in the southeastern Mediterranean.*

The exploration vessel Nautilus, with a team of experts of the University of Haifa's Leon H. Charney School of Marine Sciences, headed by Prof. Zvi Ben Avraham, discovered for the first time an area of reefs with deep-sea corals in the Mediterranean, offshore of Israel.


This area apparently stretches over a few kilometers, 700 meters under the surface and some 30-40 km off the coast of Tel Aviv. According to the researchers, this southeastern region of the Mediterranean has only sparse sea life and therefore the discovery is in fact parallel to discovering an oasis in the middle of an arid expanse. "We did not expect, know, or even imagine that we would come across these reefs and certainly not such large ones. It's like finding a flourishing oasis in the middle of the desert," said Dr. Yizhaq Makovsky, who directed the University of Haifa control center for the project.

After two and a half weeks at sea, during which time the ship's robots plunged as far as 1.7 km down into the depths of the Mediterranean, the Nautilus returned to land and the collaborative research team have begun to examine the many discoveries that they made. Probably the most significant – and most surprising – of these discoveries were the reefs of deep-sea coral, the first deep-sea coral reefs to be found offshore Israel. Their discovery has broad scientific importance. For example, they can help us in understanding the mechanisms of their survival in the environmental conditions of the deep sea, as well as unfold the history of these conditions with the effect of global changes.

"This cruise has provided a nutshell sampling of this maritime region, but our discovery only demonstrates the potential of the many surprises that await us in the depths of this area. An immediate implication of this discovery is that there is an urgent need to classify the area as a deep-sea reserve, as are other coral reef areas around the world," explained Dr. Makovsky.

In-depth research on the sea-bed samples are yet to get well under way, but additional discoveries that can already be reported from the Nautilus expedition, are two shipwrecks – probably modern boats that sunk over the past few decades; and fish and crabs that were photographed in their natural habitat for the first time, hundreds of meters beneath the Mediterranean surface.

One of the fascinating fish that were captured by the Nautilus's cameras was the Chimera Monstrosa, of the "ghost sharks" family that branched off from sharks some 400 million years ago.

The expedition also discovered and documented a 10-cm crab hiding in the recess of a rock, making it difficult for the research team to identify it. As with all the other discoveries, this crab was also documented thanks to the technological capabilities provided on the Nautilus.

Im Focus: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
