COVID-19 Threatens to Create Failings in Understanding Climate Change

Governments and oceanographic institutes all around the world have recalled nearly all of their oceanographic research vessels to home port due to COVID-19, and the impact on the ability to observe the ocean has been dramatic. According to the International Oceanographic Commission (IOC), this disruption in observation creates an ocean-data blind spot that could disrupt weather forecasts and hamper our understanding of climate change. Even where autonomous equipment such as moored buoys (fixed instruments that scan the whole water column from seafloor to the sea surface to provide a wide array of ocean data) or Argo floats (free-drifting floats that...

Pushidrosal Prepared Safe Routes for Lombok and Sunda Strait

The Indonesian Hydrography Office (Pushidrosal) conducted large hydrographic surveys between 2016 and 2017 to obtain full coverage of bathymetry and other required hydro-oceanographic data of the Sunda Strait and the Lombok Strait. The survey used modern methods and equipment from KRI RIGEL - 933 and KRI SPICA - 934, not only for study material and design exercises for the new Traffic Separation Schemes (TSS), but also to provide a high level of trust for international navigation in both straits. New TSS and other routing measures in the Sunda Strait and the Lombok Strait, all in accordance with the United Nation Convention on the... (read more)

First Fully-autonomous Shallow Water Survey

Geodata specialist Fugro has completed the Middle East’s first fully autonomous geophysical shallow-water route survey. Controlled from their remote operations centre in Abu Dhabi, an unmanned surface vessel (USV) captured a full range of geophysical data across a survey area of some 40km out from the coast of Abu Dhabi to support a client’s critical project, entirely remotely. The results of the fully autonomous geophysical shallow-water route survey comprised conductivity, temperature, depth and salinity (CTDS) profiles, bathymetry data, seabed imaging, sub-bottom profiles, and ferrous object detection such as pipes, etc. The efficiency gains and material reductions from using Fugro’s remote...

IHO Celebrates World Hydrography Day 2020

The focus of this year’s World Hydrography Day is the key role that hydrography can play in supporting autonomous technologies. This includes aerial, surface and underwater survey drones as well as autonomous ships. World Hydrography Day is an opportunity for the IHO and its 93 Member States to reaffirm their commitment to raising awareness of the importance of hydrography, and to continue to coordinate their activities. Autonomous technologies are nothing new: mariners have been using systems such as autopilots for decades. More recently, unmanned vessels such as wave gliders have helped make advances in ocean sciences. We are however witnessing increasing levels of... (read more)

Fast-moving Waterfalls in the Deep Sea

New research led by the National Oceanography Centre (NOC) has discovered how fast-moving waterfalls under the sea control the shape and behaviour of submarine channels. These underwater channels are the offshore equivalents of rivers, but can be much larger. Submarine channels can extend for tens to thousands of kilometres offshore, providing an important conduit for the transfer of sediment, nutrients and pollutants, such as microplastics, to the deep sea. Avalanches of sediment that flow down these channels also pose a hazard to networks of seafloor cables that underpin global communications, including the internet. An international research team, including NOC, the... (read more)

COVID-19 and Deep Ocean Research

Due to the COVID-19 global pandemic, several researchers around the world have initiated investigations to understand the correlation between virus dispersion and environmental factors such as climate change and the anthropogenic impact in the modification of ecosystems, as well as the risk of new pandemics appearing. In this scientific field – so relevant to humanity – it is necessary to take into account oceanic research and consider investigations in the deep areas of the oceans. In the abyssal zones of the oceans, as is well known to the oceanographic community, thermohaline circulation takes place, which slowly renews the water masses in all the... (read more)

Using Unmanned Surface Vehicles for Bathymetric Dam Imaging

A North American Case Study with Wide-ranging Applications
Inspection of dams is a high-risk task for divers because of strong currents and eddies. The use of emerging technologies such as unmanned surface vehicles equipped with echosounders and sonars can lower those risks. Such systems can perform subsurface dam inspections quickly and effectively without putting humans at risk, as this US case study shows. Overused roads, outdated railway systems, brittle power grids, crumbling bridges and suchlike all take a toll on the economy and, tragically, sometimes even lead to loss of life. Failing infrastructure is an issue for most countries, and likely more so in developed nations that still... (read more)

Colombian Naval Academy Certifies Category “A” Hydrographers for the First Time

The Colombian Navy has successfully concluded its first category “A” hydrography course. This course, which was recognized by IBSC in 2018, was completed by 15 naval officers at the “Almirante Padilla” Naval Academy (ENAP). This means that the institution is now able to provide hydrography training for personnel in Colombia, to the high standards established by the IHO for the exercise of their role in the national hydrographic service, within the national maritime authority (DIMAR). Previously, personnel received category “A” hydrography training in other countries such as the United States or Chile. The certification ceremony was presided by the Rear... (read more)

New IHO Guidelines for Hydrographic Geospatial Data

The IHO has published new guidelines for the development of product specifications for the creation of hydrographic geospatial data. Modern navigation systems and geospatial solutions use digital data from a variety of sources. In order to facilitate the integration of hydrographic data and applications, the IHO developed S-100, a hydrographic geospatial data standard that can support this array and that is fully aligned with international geospatial standards, in particular the ISO 19000 series. The aim of the new S-97 guidelines is to assist in the creation of harmonized product specifications utilizing S-100 for implementation within the e-Navigation ecosystem. This encompasses all product specifications... (read more)

Luigi Sinapi Elected as New IHO Director

Following the postponement of the IHO Assembly due to the Covid-19 pandemic, the IHO Secretariat initiated a remote voting procedure to fill the position of IHO Director, which will become vacant in September 2020. As a result of this process, during which Member States could vote by either paper or electronic ballots, Rear Admiral Luigi Sinapi from Italy has been elected as the new director.  Rear Admiral Luigi Sinapi has been director of the Italian Hydrographic Institute of the Navy since 2015, and as such has worked closely with the IHO and its various bodies for many years.
