The Impact of Future Global Tides on Energy

 The first comprehensive study of the impact of global sea-level rise on tides has implications for future coastal flood risk, harbour management, and the long term planning of tidal energy sites.    This research, published in Continental Shelf Research by scientists at the National Oceanography Centre (NOC), University of Southampton and Deltares, shows that sea-level rise can significantly alter tides across the world in many different ways in both space and time.    The change will be most pronounced in shelf seas on the east coast of the Americas, northwest Europe, north coast of Russia, across Asia and Australasia.   Professor Kevin Horsburgh, a co-author on the paper from the NOC, said “This research shows that the tides that many people think of as constant can be affected by climate change and sea level rise”   This study was conducted by feeding a range of ‘plausible’ estimates of global sea level rise, considered by the Intergovernmental Panel on Climate Change (IPCC), into a model of global tides. Scenarios ranging up to 10m of sea level rise were tested however the results for 0.5, 1 and 2 meters of sea level rise are of the most societal relevance.    The study also considered the effect of fixed and receding coastlines and the effect of non-uniform patterns of sea level rise associated with melting of the polar ice sheets.  


Sea Level Rise ‘Worst Case Scenario’

A paper published this week in Environmental Research Letters by NOC scientist Dr. Svetlana Jevrejeva provides new information about the probability of a sea-level rise reaching of 180cm by 2100. In this study Dr. Jevrejeva and colleagues explore the range of possible sea level rise by 2100 and add new data to the estimates currently available. Previously an upper limit, or ‘worst case scenario’, has not been possible to calculate

Accelerating Sea Level Rise Threatens Coasts

Sea level rise in the past two decades has accelerated faster than previously thought in a sign of climate change threatening coasts from Florida to Bangladesh, a study said on Wednesday.   The report, reassessing records from more than 600 tidal gauges, found that readings from 1901-90 had over-estimated the rise in sea levels. Based on revised figures for those years, the acceleration since then was greater than so far assumed.  


Sea-Level-Rise Forecasts Major Climate Impact to Pacific Islands

Dynamic modeling of sea-level rise, which takes storm wind and wave action into account, paints a much graver picture for some low-lying Pacific islands under climate-change scenarios than the passive computer modeling used in earlier research, according to a new U.S. Geological Survey report. A team led by research oceanographer Curt Storlazzi of the USGS Pacific Coastal and Marine Science Center compared passive "bathtub" inundation models with dynamic models for two of the


NOAA: US to See More Floods from Sea Level Rise

Most of U.S. coast may see 30 or more days a year of floods up to 2 feet above high tides. By 2050, a majority of U.S. coastal areas are likely to be threatened by 30 or more days of flooding each year due to dramatically accelerating impacts from sea level rise, according to a new NOAA study, published in the American Geophysical Union’s online peer-reviewed journal Earth’s Future. The findings appear in the paper From the Extreme to the Mean: Acceleration and Tipping Points


Expedition to Glaciers of Antarctic

How has the West Antarctic Ice Sheet changed in response to alternating warm and cold time periods? And what does it mean for the sea level – today and tomorrow? Pursuing answers to these key questions, 50 researchers on board the Alfred Wegener Institute’s research vessel Polarstern are going to depart from Punta Arenas (Chile) on 6 February 2017, bound for the Amundsen Sea – the region of the Antarctic currently characterised by the most massive and rapid loss of ice


Singapore to Adopt Dutch Polder Concept for Reclamation

Singapore has announced it will build a polder designed by Royal HaskoningDHV with local partner Surbana Jurong that will add 810ha to Pulau Tekong, one of Singapore’s largest islands. Traditionally, sand has been used to fill the area to be reclaimed above sea level. This new approach involves building a dike around the area to be reclaimed and draining the water from it – a 400 year old Dutch proven method


Indonesia Building Sea Wall to Protect Jakarta

Indonesia on Thursday officially launched a $263 million project to build a giant sea wall along the coast of its capital, Jakarta, in an attempt to protect businesses and homes from flooding. Last year's rainy season brought Jakarta to a standstill, causing a river in the city to breach its banks and swamp the central business district, leaving thousands stranded and causing $580 million in damage. With 40 percent of Jakarta already below sea level


The Arctic Is In Meltdown

 The Arctic has lost almost 95% of its older ice cover since 1984, says NASA. The area covered by Arctic sea ice at least four years old has decreased from 1,860,000 square kilometres in September 1984 to 110,000 square kilometres in September 2016.   ABC News quoted a report produced by the Arctic Council -- an intergovernmental forum of eight member countries that include the U.S., Canada and Russia -- stressed that changes to the Arctic have "global implications

Giant Iceberg Breaks off Antarctica

Darker colors are colder, and brighter colors are warmer, so the rift between the iceberg and the ice shelf appears as a thin line of slightly warmer area.

One of the biggest icebergs on record has broken away from Antarctica, scientists said on Wednesday, creating an extra hazard for ships around the continent as it breaks up.   The one trillion tonne iceberg, measuring 5,800 square km, calved away from the Larsen C Ice Shelf in Antarctica

The rapid loss of Arctic sea ice is a sentinel. Most of us will never venture into the Arctic, but it can and does provide us with a forewarning of impacts coming to our parts of the Earth – and some of the most significant impacts will directly affect the maritime industry.  


El Nino Signal is Weakening in the Pacific

The probability of El Nino, a warming of ocean surface temperatures in the eastern and central Pacific, developing this year has been downgraded by U.S. government forecasters as sea surface temperatures and wind speeds in the area remain close to their long-term averages.
