Unprecedented Deep-Sea Shark Discovery in Israel

Spare us the climate nonsense.  What we have here is a deep sea sinkhole allowing a brine pool and methane ecology to live there.

This must be replicated glpbaslly and they need to be sought out.  And yes they provide a possible stable collection zone with plausible time lines as well.  This can be as good as tree rings though hardly as precise.

However million year linages become plausible as well with likely thousands of such beds to core.  All this can salso be compared to the deep sea ooze.

Unprecedented Deep-Sea Shark Discovery in Israel Sheds Light on World’s Understanding of Climate Change

Research led by University of Haifa reveals hundreds of sharks and one of the largest deep sea concentrations of shark eggs ever found, providing a unique opportunity to better understand the deep sea.

New York, NY, August 11, 2021 — A research initiative led by the University of Haifa-and partners in the Eastern Mediterranean Sea recently revealed deep sea brine pools and related habitat hotspot, including hundreds of deep-water sharks and the largest concentration of deep sea shark eggs ever found. These represent one of the most significant discoveries of marine habitats in Israel’s history, with potentially important implications for the world’s understanding of climate change.

In an expedition off Israel’s coast that is part of a long-term collaboration among University of Haifa’s Leon H. Charney School of Marine Sciences, the Israel Oceanographic and Limnological Research, Ben-Gurion University of the Negev, and the Inter-University Institute of Marine Research, researchers uncovered a biologically diverse paradise including a rich food web based on methane as well as the sharks and the shark nursery.

Notably, as one of the planet’s most sensitive areas when it comes to climate change, the Eastern Mediterranean lends substantial insight into conditions that other regions may experience in the future.

“From a global marine research perspective, this discovery can have enormous implications,” said the Charney School’s Dr. Yizhaq Makovsky, one of the initiative’s leading researchers. “The Eastern Mediterranean Sea can be regarded as an early-warning system for what we can expect from marine environments across the world. Therefore, we believe that our discovery of a previously unknown deep-sea hotspot of life could provide crucial information for the sustainability and resilience of the marine ecosystem not only in the Eastern Mediterranean, but also globally in other oceans.”

The deep-sea research initiative is aligned with University of Haifa’s academic vision, towards achieving the UN Sustainable Development Goals, specifically focusing on SDG14: “Life Below Water” -aiming to save the ocean and its biodiversity and increase marine protected areas.

“The deep sea is the Earth’s climatic capacitor, mitigating short-term changes,” Makovsky said. “Once the impact of surface synoptic changes migrates to the deep sea, the entire climate of the Earth changes. The Eastern Mediterranean Sea experienced multiple climatic and anthropogenic changes at different time scales. Investigating the geological and environmental records concealed in this hotspot will provide a high-resolution record of the impact of changes on the deep sea, which is essential for understanding local and global climatic changes.”

“This is a shocking revelation to those who are familiar with the Eastern Mediterranean, which was thought of as an ocean desert,” Makovsky explained.

Yet the shark nursery, the expedition revealed, had existed for a long period of time before it was exposed. In fact, the hotspot could be the region’s largest mating location for these deep-sea sharks.

“This was happening under our noses for thousands of years, right next to Tel Aviv, one of the largest cities in Israel,” said Makovsky. “It was hiding in plain sight, which highlights how little we know about the deep sea — not just off the coast of Israel, but around the world. This is a global challenge.”

The discovery, which harnessed modern and innovative technological capabilities developed at the Charney School over the course of a decade, was made after years of geo-mapping work beneath the ocean’s surface. The specific study which led to the discovery was originally set into motion when famed oceanographer Dr. Bob Ballard visited his long-term partner, Prof. Zvi Ben-Avraham, in Israel. Ben-Avraham and Ballard helped promote deep-sea research in the southeastern Mediterranean, which previously was barely existent.

“This discovery closes the loop on a decade of exploration,” Makovsky said. “When I first met Dr. Ballard, only a decade ago, I became hooked on the deep sea. In Israel, we did not know much about deep-sea exploration back then. Since then University of Haifa’s Charney School transformed into the state-of-the-art center for deep-sea research that it is today.”
