APAC region gaining local access to ScanFish ROTV rental and support
With a rapid increase in the offshore wind market, the Asia-Pacific (APAC) region has seen an increasing demand for ScanFish ROTVs, one of the most commonly used sensor platforms for UXO surveys around the world, developed by Danish maritime engineering company, EIVA. To meet this need efficiently and at lower cost to survey companies, EIVA has shipped a fleet of new ScanFish ROTVs and other rental equipment to their offices in Singapore, where their APAC team operates. EIVA’s rental equipment is therefore ready to be delivered more easily to customers within the APAC region, sent out from Singapore.
‘Our customers operating in Asia have emphasised the importance of making ScanFish ROTVs more accessible in this region. We have therefore been working over the past years to ensure our Singapore offices have the rental equipment and man-power needed to support them together with our reps in Japan, Indonesia, China and Malaysia.’ Julie Rydberg Sørensen, Technical Sales Manager – Rental | Team Lead, EIVA, who runs the rental activities worldwide, including in the APAC region.
For seabed survey companies operating in the APAC region, shipping times will be reduced by several weeks compared to when shipping out of EIVA offices in Denmark. In addition, heavy equipment can be shipped via sea-freight rather than air-freight for a more cost-effective solution, while keeping shipping times reasonable.
Not only will rental equipment ship out of Singapore, but EIVA’s team there will be able to offer servicing for the ongoing rental jobs. The Singapore-based team, which provides local support for EIVA’s customers in the region, includes Asia-Pac Area Sales Manager, Nge Aik Moh, and customer support engineer, David Thomson, both of whom have a wealth of experience to understand the needs of surveyors in this region. This team shares offices with sister company Sonardyne, whose positioning sensors are used on EIVA solutions such as ScanFish Equinox, providing a centralised location for survey equipment support and services in this region.
Fugro leads large-scale seafloor mapping project to protect Florida’s coast

Omicron Connectors Facilitate Cutting Edge Camera System for BBC Studios new landmark underwater TV series
Teledyne Impulse-PDM, a leading provider of high-performance interconnect solutions, has supplied its state-of-the-art Omicron optical fibre connectors to BBC Studios for use in their upcoming underwater natural history series, set to air in 2026. Filming required custom-built camera technology designed to capture extraordinary marine footage from the depths of the Arctic, facilitated by the Rev Ocean’s Aurora ROV.
To capture groundbreaking underwater content BBC Studios and Marine Imagine Technologies designed a deep ocean-rated camera system integrated with a telemetry bottle, the central hub for communications on the submersible. However, during the Arctic expedition, the crew encountered challenges connecting the camera system to the ROV’s telemetry bottle due to a missing optical fibre connector, critical to establishing communications for the system. Without this essential part, the team faced a significant delay in capturing underwater footage.
BBC Studios reached out from their expedition for support and Teledyne Impulse-PDM rapidly supplied the Omicron 5030/5070 optical connectors which deliver high-performance fibre connectivity in demanding environments.
Suitable for both single-mode and multi-mode operation, Omicron connectors were ideal for the BBC Studios deep-sea application and the stringent requirements of the Aurora ROV system. Despite a tight timeline, Teledyne Impulse-PDM was able to courier the connector to Svalbard, enabling the BBC Studios research crew to proceed with their mission.
The BBC production team praised Teledyne Impulse-PDM’s prompt support, stating, “Teledyne’s Omicron connectors were integral to keeping our project on track, and without the Teledyne team’s quick response, we would not have been able to film in time.”
Commenting on the project, Carolyn Jones, Head of Business Operations for Teledyne Impulse-PDM, said, “We’re delighted to support BBC Studios in their quest to capture the world’s natural wonders. Our Omicron connectors are specifically designed to perform reliably in the challenging conditions of deep-sea exploration, and we’re proud that our technology played a role in keeping this extraordinary project on schedule.”

The company's products have proven their performance, even in the most demanding applications, which include oceanographic exploration, defence, offshore energy, medical devices, nuclear systems, and wastewater management.
Southern Ocean study challenges key carbon pump theory
A new UK National Oceanography Centre (NOC)-led study has put a major question mark over the role a unique group of tiny microscopic plants plays in driving ocean carbon storage.
Diatoms, a type of plankton or marine algae, have a significant role in drawing carbon down into the deep, especially in the Southern Ocean, which takes up about a third of organic carbon stored in the ocean.
Uniquely, diatoms have dense, silica-based exoskeletons – like miniature glass houses – which were thought to provide ballast, making them prone to sinking and, therefore, a key way carbon is transported to the deep ocean.
But the new study, based on data from two major expeditions to the Southern Ocean’s underexplored twilight zone – the region between ~100 m to 1,000 m deep – found that the diatom skeletons lingered near the sea surface while carbon made its way to the deep ocean by other means.
“The ocean plays a key role in the global carbon cycle, with tiny, microscopic plants taking up billions of tons of carbon from the atmosphere every year,” explains research lead Dr Sari Giering, research lead at NOC. “For years it has been believed that this group of plankton – diatoms – play a crucial role in efficiently transporting carbon to the deep ocean, where it is held out of contact with the atmosphere.
“The surprising discovery that diatoms’ silica skeletons stay near the surface while carbon makes it down to the deep ocean forces us to rethink the ecological processes in what we call the biological carbon pump.”
The biological carbon pump describes a collection of processes in which plankton take up carbon in surface waters and shunt this carbon to the deep ocean. These natural processes store billions of tonnes of carbon in the ocean each year.
“Previous studies have looked at what has ended up at the seabed, which shows carbon is making its way there typically with the aid of ballast material, such as diatom’s silica-based skeletons,” adds Dr Giering.
“But our research, looking at what happens within the twilight zone before carbon reaches the seabed, shows that diatoms are at times not contributing as heavily to the Southern Ocean’s carbon pump, as had been thought. This means there are unknown or poorly measured processes happening in the deep ocean that we need to learn more about.”
A concern has been that ocean warming could impact diatom productivity and therefore reduce the strength of the biological carbon pump in the Southern Ocean.
“The Southern Ocean is vulnerable to ocean warming, which may alter the availability of nutrients and reduce diatom numbers in future,” says lead author Jack Williams, a post-graduate researcher at the University of Southampton. “But our results suggest these changes may not impact the strength of Southern Ocean carbon storage as much as previously thought.
“On the other hand, carbon is still making its way to the deep, so there are unresolved processes at play in the twilight zone that we need to learn more about. Understanding these processes and how they govern carbon uptake in this hugely important part of the ocean is crucial for accurately predicting how the oceans may store carbon in the future.”
The research was conducted as part of two major NOC-led initiatives, Controls over Ocean Mesopelagic Interior Carbon Storage (COMICS) and Carbon Uptake and Seasonal Traits in Antarctic Remineralisation Depth (CUSTARD). These projects were funded by the UK’s Natural Environment Research Council (NERC) and the
European Research Council grant Advancing Novel imaging Technologies and data analyses in order to understand Interior ocean Carbon Storage (ANTICS).
Over two expeditions, each lasting more than five weeks at sea, NOC scientists and international colleagues studied the twilight zone at four different sites in the Atlantic and Pacific sectors of the Southern Ocean.
This included iron-rich waters around a remote chain of islands and nutrient-starved waters in the open ocean. The collaborative team used a combination of innovative techniques, including ship-based measurements, mooring arrays and autonomous underwater technologies.

Tuco Marine has delivered their reliable ProZero vessels for use in offshore wind farms, environmental surveys, defence and aquaculture.
The quality of data delivered with this system also benefits from positioning and imaging sensor technologies thanks to strong partnerships within the international Covelya Group. EIVA’s sister companies in this group include sensor providers Sonardyne and Wavefront Systems, as well as Forcys, which provides defence expertise for customers seeking to deploy this technology for mine countermeasures, rapid environment assessment and more.
NOC scientist Dr Elizabeth Kent recognised with MBE
The UK National Oceanography Centre’s (NOC) Dr Elizabeth Kent has been awarded an MBE, for services to tracking global temperatures, recognising her decades of research into improving historical sea surface temperature records.
The award was announced in King Charles III’s New Year Honours list, which recognises the outstanding achievements of British citizens, recommended by the prime minister following an independent assessment process.
For over three decades, Liz, who is Associate Head of the Marine Physics and Ocean Climate group at NOC, has performed research that underpins development of long-term global surface temperature records, helping to make them more accurate and consistent - crucial to the ability of the international science community to detect and describe human-induced climate change.
This research, and the datasets built upon it, underpin climate assessments such as the Intergovernmental Panel on Climate Change (IPCC) Assessment Reports, used by every policymaker, campaigner or researcher who wants to know or to show how the ocean and climate is changing.
Liz is part of a team at NOC working on historical marine surface observations. She has spent years studying the details of the observations, how they were made, recorded and stored. This insight helps reveal the true variations in marine surface temperature by reducing the impact of spurious effects such as changing measurement methods over time.
By examining the origin and uncertainty of every measurement of sea surface and air temperature from commercial, naval and research ships since the 19th Century, Liz has been integral in ensuring the science community have access to the highest quality information possible.
Commenting on her award, Liz said: “I am honoured that my contribution to improving historical marine data has been recognised in this way. This wouldn’t have been possible without the long-term support that the National Oceanography Centre provides for this work.
NOC Chief Scientist Prof. Penny Holliday said: "Liz has been instrumental in ensuring that the sea surface temperature datasets used globally are as accurate as possible. Her expertise helps to ensure that hundreds of years of historical temperature data are continually improved and better understood, enabling us all to have the highest quality data when investigating global climate change.”
The award of an MBE furthers Liz’s national and global reputation as an innovative and world-leading researcher, which has previously been recognised by the award of the Royal Meteorological Society's Adrian Gill Prize for 2013.
