By harnessing capabilities of advanced satellite technology and ever-evolving data analysis, satellite-based mapping (including satellite-derived bathymetry, SDB) offers an efficient, extensible and cost-effective method for mapping water properties, underwater topography...

The presence of suspended sediments in water bodies presents significant challenges for the dredging industry. Existing methods to determine nautical depths are intrusive single point methods relying on in situ density or shear strength measurements1,3 or low-frequency single-beam echosounder recordings1,2. The use of single-beam echosounders is however systemically problematic as they are not practical in satisfying the CATZOC A1 coverages required for contemporary electronic navigational charting.

The AquapHOx underwater long-term loggers enable accurate and higly resolved total pH measurements, long-term O2 monitoring and trace O2 detection. They are available as single analyte shallow water and flexible deep-sea multi-analyte loggers. The cost-effective and easy-to-operate deep sea logger allows to measure O2 or total scale pH with the same compact instrument succesively. Simply exchange the sensor head, choose between different analytes and sensor formats and deploy down to 4000m water depth. For advanced underwater applications, PyroScience recently launched the unique all-in-one AquapHOx platform for monitoring critical parameters and their dynamics underwater; in open ocean, the deep sea, coastal ecosystems, rivers, lakes...

The term ‘sediment waves’ was fully established in a special issue of Marine Geology and refers to large-scale depositional bedforms in various parts of the world’s oceans. These undulating objects...

Activities such as sand extraction, cable trenching and pipeline construction regularly churn up the top layer of the North Sea seabed. However, this top half metre is an important habitat for all...

When contemplating the replacement of a research and survey fleet, a collective effort is required to meticulously curate an optimal new fleet, considering factors such as ship type, size, capabilities...

World oceans host diverse creatures that shape the seafloor. In a groundbreaking interdisciplinary study published in Communications Earth & Environment, Kiel University geoscientists, alongside biology and oceanography experts, have linked...

In a second seafloor survey off the Southern California coast, researchers from UC San Diego’s Scripps Institution of Oceanography uncovered a staggering 350 square kilometres of discarded military munitions. The April...

Aquatec Group has expanded the 'Sediment? Solved' range to include instrumentation to measure surface sediment stability, with the addition of Partrac’s benthic flumes and Cohesive Strength Meter (CSM). The Cohesive...
