most comprehensive program to date.On the opening day of the show, Monday, 25 February 2019, the one-day Ocean Futures Forum (new to OiA) will comprise a series of presentations and panel discussions examining anticipated issues, requirements and developments relating to aquaculture, ocean and coastal infrastructure protection, offshore marine renewable energy and the overall Blue Economy. Confirmed presenters include Wendy Watson Wright, CEO, Ocean Frontier Institute; Plenary Co-Chair Rick Spinrad, President, Marine Technology Society (MTS); and Jason Giffen, Assistant Vice President, Planning &

techniques by leveraging machine learning and computer vision technology to enable accurate depth retrieval in variable water conditions.If successful, TCarta said, these enhanced bathymetric techniques will have positive impacts on operations related to oil and gas exploration and production, coastal infrastructure engineering, environmental monitoring, and geointelligence (GEOINT) activities.“Our goal with Project Trident is to expand the geographic scope of SDB in shallow coastal areas,” said Kyle Goodrich, TCarta President. “SDB technology currently derives water depths only in

NOC Predicts Increase in Extreme Sea Levels

A new study has predicted that future global warming will lead to an increase in ‘extreme sea levels’, with consequent flood risks to coastal infrastructure and human populations. Extreme sea levels occur through a combination of high tides and extreme weather events, which can generate storm surges and high wind waves. These incidents are intensified by gradual rises in mean sea level and predicted increases in tropical cyclone activity. Researchers have taken all these factors into account to assess future risks of extreme sea levels up until the year 2100. The National Oceanography

;s most urgent challenges. Science at Scripps informs urban-, state-, national- and international level policy and planning. As one example, in last year’s El Niño season Scripps performed ultra high-resolution coastal elevation surveys that are helping the U.S. Navy understand risks to coastal infrastructure and the possible relocation of facilities affected by sea-level rise. Californians see the impacts of environmental change every day. Many at Scripps are involved in research to better understand the ocean and the atmosphere with projects to improve our ability to forecast change, describe

Study to Examine Impacts of O&G Rock Dumping

fragmented smaller banks formed as a result of tidal processes as well as biogenic (Sabelaria spinulosa) reefs.    Intertek Energy & Water will use its extensive knowledge of the physical and biological environment of the North Sea, gained from 30 years working on marine and coastal infrastructure projects, to deliver this study for JNCC. The study will compare typical sediment profiles and characteristics associated with oil and gas rock dumping operations, with those within North Norfolk and Saturn Reef cSAC/ SCI. It will also assess the potential physical impacts that rock dumping

off shore,” said Bechle. “We thought of them as rare. And it’s true – events of that magnitude are quite rare. But with this study, we wanted to get a picture of the more moderately sized events. A one-foot water level change over a short time period can be dangerous for coastal infrastructure and can cause coastal bluff erosion, dangerous rip currents and nearshore sediment transport.”   Often mistaken for seiches (another type of wave), meteotsunamis are single waves similar to, but smaller than, tsunamis caused by earthquakes or landslides. Instead of being caused

Fugro is coupling current and wave models with sediment transport modules to derive the sediment pathways and identify the erosional and depositional areas to be considered in the planning and design of port and coastal infrastructure. The team is also addressing the impact that the construction of industrial infrastructure, such as a desalination or power plant, has on the quality of coastal waters
