A project monitoring the water quality during the renovation of the old warehouse city of Hamburg - a heritage resting on aged oak poles - is managed by MacArtney Germany.
As of 2015, the world's largest complex of warehouses, Speicherstadt Hamburg (warehouse city, Hamburg), is a UNESCO World Heritage Site. Speicherstadt's beautiful neo-gothic red-brick architecture and winding network of streets, fleets and bridges erected into the Elbe river is an 'extraordinary example of representing the value of trade in Hamburg during its foundation.
The Speicherstadt, built between 1885 and 1927, rests on thousands of oak poles that have deteriorated over time due to a slow advancing bacterial decomposition and indentation of the fleet bed as a result of an expanded tide difference.
Renovation work is necessary to prevent the poles from sinking towards the fleets, including bed reconstruction arrangements raising the fleet bed by 0.5 to 1.5m and supply of bearing sand. Furthermore, the bed is stabilised with cement.
Incorporating these measures - a process ranging from Fall 2020 to Summer 2021 - necessitates an accompanying water quality monitoring, especially controlling and remedying any impacts on the water quality caused by the cement placement.
For this purpose, nine EXO1 Multiparameter Sondes from US manufacturer YSI are placed in different locations close to the ground on the existing fleet poles. The EXO 1 Sonde measures temperature, conductivity, pH value, dissolved oxygen content and turbidity every 5 minutes over several days and time sequences. The sondes feature internal data storage and power supply for autonomous operating.
MacArtney Germany was commissioned to take on the supply of the multiparameter sondes, including a measurement and service concept for the project and all planning plus execution of the water quality measuring. This involves regular calibration and maintenance of the sondes in the in-house workshop, data provision and installation and de-installation of the sondes on-site.
Working in the fleets requires flexibility and swiftness. The environment is tide dependent, generating relatively short time windows following the water level. The water quality measurements were conducted throughout the renovation work, with brief interruptions for calibration, processing and data evaluation.
Marine robotics to help uncover hidden link in glacier melting
On Friday 13th August 2021, Marine scientists deployed robotic vehicles on a dangerous mission to the face of a glacier in Svalbard as they attempt to expose the hidden link in how rapidly melting Arctic ice is changing our ocean.
The mission to Ny Ålesund, the world’s most northerly settlement, is a collaboration between the Scottish Association for Marine Science (SAMS), UiT The Arctic University of Norway, the Norwegian Polar Institute and University Centre on Svalbard. The team will examine the Kronebreen glacier in Kongsfjorden, measuring the freshwater run-off as it melts, and assessing how it interacts with the saltier sea water coming into the fjord from the North Atlantic.
Humans are unable to sample at the glacier face because of the risk of huge chunks of ice collapsing into the sea below, a process known as glacier calving.
Instead, the team will use an autonomous surface vehicle (ASV) built by Norwegian company Maritime Robotics, to record various oceanographic measurements at the face of the glacier, while an autonomous underwater vehicle, known as an ecoSUB, will take temperature, salinity and oxygen readings below the surface. Meanwhile, aerial drones will survey the so-called freshwater ‘plumes’ that run off from the glacier.
Lead scientist Prof Finlo Cottier of SAMS said:
“Fjords are the connection between the changing ocean and our rapidly melting northern glaciers. The transfer of heat and water at these points, often just a few kilometres wide, are therefore extremely important in understanding how climate change is impacting our ocean.
However, as these areas are too dangerous to survey fully and too small to be picked up on global ocean models, the interactions between fjords and glaciers have not been sufficiently represented in ocean and climate predictions. We need to know much more about the fresh water coming into the ocean: How much is there? Where does it end up? How does it move?It would simply be too dangerous to go into such a hostile and remote environment with a boat. Not only is there a risk of falling ice, but large-scale calving causes huge waves, so it is a dangerous place. That is where the robotic systems come into their own, working at the front line of Arctic science.”
While rising global temperatures increase glacial melt, glaciers are also breaking up below the surface of the water. In a process known as sub-glacial discharge, melt water flows down through the glacier and out into the ocean. This water is fresher than the surrounding sea water, so starts to rise in the water column, creating a plume that pulls in warmer Atlantic water which increases the melt rate at the face of the glacier. This process undermines the wall of ice, causing huge chunks to collapse into the sea.
The marine robotics deployed by the team will collect crucial data to improve our understanding of this process.
The mission is scheduled to last seven days and the team, which includes SAMS Prof Mark Inall and University of the Highlands and Islands PhD student James Coogan, will be based in Ny Ålesund, making daily visits to the glacier.
SAMS has close links with project partner UiT The Arctic University of Norway: Prof Cottier has an adjunct professorship at the Norwegian institute, while UiT’s chief technician for the ASV Dr Emily Venables was previously part of the SAMS robotics team.

Metocean studies underway for first floating wind farms in Welsh waters
A metocean study supporting the design of the first floating offshore wind (FLOW) projects in Welsh waters is underway.
Blue Gem Wind (BGW), a joint venture between Simply Blue Energy and TotalEnergies, is the developer behind two Celtic Sea floating offshore wind projects, Erebus and Valorous.
BGW has appointed ABPmer to deliver the certifiable metocean design bases to inform front end engineering design (FEED) and Detailed Design for both projects. This includes the production of fully calibrated spectral wave and hydrodynamic hindcasts.
Heidi Roberts, Head of Modelling and Physical Processes at ABPmer, said;
“Alongside our physical process work to support the consenting of Erebus, we are thrilled to continue working with BGW on these exciting projects.“
“We will refine our existing models using ABPmer’s SEASTATES hindcast database, enabling us to fully represent the regional oceanographic conditions and nearshore processes, providing a bespoke 40-year hindcast of both hydrodynamics and waves. Detailed metocean analysis will then be completed on the calibrated hindcast and metocean design bases produced.”
The study will provide extreme and operational metocean criteria for the array and export cable corridors for both projects, with delivery in late summer 2021.
ABPmer’s metocean consultants use the global SEASTATES hindcast models and extensive suite of metocean analysis software to support projects worldwide.
