Mysterious ‘Hob Blob’ Is Drifting in Pacific Ocean, Near New Zealand

Weather specialists have finally given a cause for the mysterious event in the Pacific Ocean known as the ‘Hot Blob.’ ​The enigma around this massive hot blob drifting close to New Zealand was intensely scrutinized after it was found in the summer.

An increase in water temperature of about 6 degrees Celsius above average in a vast region of the Pacific Ocean is now thought to have been lead to an ‘anti-cyclone’ weather network, a renown scientist says. Depicted on heat maps as a deep red blob, the spot extends at least a million square kilometers.

Mysterious ‘Hob Blob’ Is Drifting Near New Zealand

Professor James Renwick, the chief of Geography, Environment and Earth Sciences at Victoria University in Wellington, said the level of the temperature increase close to the remote Chatham Islands archipelago was shocking.

James Renwick said: “It’s the biggest patch of above-average warming on the planet right now. Normally the temperatures there are about 15C; at the moment, they are about 20C.”​

Professor Renwick claims that the hot blob could be connected to the increased atmospheric greenhouse gas emissions. The weather specialist said that the phenomena happened mainly because of a merging of a powerful high-pressure system and a lack of wind.

He added: “It’s not uncommon to see patches of warmer water off New Zealand, but this magnitude of four, five, up to six degrees is pretty unusual. It’s probably a very thin layer of the ocean that has warmed up, and there hasn’t been any wind to cool it for several weeks.”

The Warmest Decade Ever Recorded

Anti-cyclones take place when an accumulation of air cools, shrinks, and becomes thicker. This, then, enhances the weight of the atmosphere and the surface air pressure. Professor Renwick believes that an increase in ocean temperature in a relatively short time could be challenging for aquatic life if it happens in a place deep within the sea.

Such regions are not so impacted by severe temperature changes than those on land because of the larger quantity of energy required to warm a vast mass of water. The weather expert noted that scientists would keep observing the temperature increase in the following weeks to understand more about the hot blob’s origin and how it affects the surrounding area.

The mysterious phenomena appeared after a marine heatwave two years ago, concurrent with New Zealand’s hottest summer ever recorded. Over 3 degrees Celsius above average, the temperature led to the finding on Australian tropical fish thriving by New Zealand’s coast.

The World Meteorological Organization (WMO) has reported that this decade was most probably the hottest period ever recorded on Earth for both land and oceans. Seawater has later on demonstrated to have grown more acidic after being polluted with plastic junk and carbon dioxide from the atmosphere.

Temperatures for this decade were about 1.1 degrees Celsius above average for the pre-industrial time frame. The initial discoveries of the WMO’s annual condition of the global climate report published earlier this month noted that this year was likely to be the second or third warmest ever recorded on Earth.
