Water column data acquired by multibeam echosounders (MBES) imposes large requirements on disk storage and data transfer, so is typically logged only during specific times, a practice that poses the risk of missing interesting targets. Furthermore, huge data volumes from both bathymetry and water column data can lead to huge burdens for the operators during long surveys. MBES data is often compressed using standard solutions such as Zip or 7-Zip, but these can be computationally heavy for a relatively modest size reduction. To overcome this, we developed FAPEC, a high-performance data compression software, now supporting MBES data. We also present FARSHY, a fast visualization and analysis tool to

https://www.uksailmakers.com/encyclopedia/glossary/depression/
En meteorología, una depresión se refiere a una zona de baja presión en la atmósfera, caracterizada por el ascenso del aire, la formación de nubes y, a menudo, asociada a condiciones meteorológicas inestables como lluvia, vientos fuertes y tormentas. Las depresiones, también llamadas ciclones en términos meteorológicos, se forman cuando el aire cálido y húmedo asciende, provocando una caída de la presión atmosférica. Estos sistemas son comunes en latitudes medias y suelen atravesar océanos y continentes, influyendo en los patrones meteorológicos y afectando las condiciones de navegación.
Comprender las depresiones es esencial para los navegantes, ya que los sistemas de baja presión pueden provocar cambios meteorológicos rápidos y severos, que afectan la visibilidad, la dirección del viento y el estado del mar. El estudio

Industry survey 2024
How do you perceive prospects in the hydrographic surveying industry in 2024, compared to the past couple of years? When contemplating the hydrographic sector holistically, which areas of investment do you foresee experiencing the most noteworthy developments in the coming years? Will there continue to be a surveyor on board at any stage of the survey process? How do you plan to select and retain new surveyors for the next decade? In what ways do developments such as climate change and sustainability impact your organization’s operations? How can the hydrography sector draw insights from other industries? What are the most significant challenges currently facing businesses? Which phase of the survey project poses the

A las 8:00 a. m. del 24 de noviembre, el centro de la depresión tropical se encontraba aproximadamente a 9,5 grados de latitud norte y 128,4 grados de longitud este. Se pronostica que, en los próximos uno o dos días, la depresión tropical se desplazará en dirección oeste-noroeste a una velocidad de unos 20 km/h.
Entre la noche del 25 y la madrugada del 26 de noviembre, la depresión tropical penetrará en el Mar del Este. El 26 de noviembre, cuando se encuentre

News
Exail, together with its partner Thesta, has delivered a DriX H-8 uncrewed surface vessel (USV) to Orlen Petrobaltic. This marks the very first commercial deployment of DriX in Poland, where the complex maritime environment of the Baltic Sea demands innovative and resilient solutions for offshore operations.
The Exail’s DriX H-8 USV is known for its robustness, endurance and ability to deliver high-quality hydrographic and geophysical data. With its autonomous capabilities and ability to operate in challenging offshore conditions, the DriX H-8 offers a safer, more efficient and environmentally friendly alternative to traditional crewed vessels.
First-time integration
Orlen Petrobaltic will deploy the DriX H-8 in the Baltic Sea to support offshore platform activities. For this project, the DriX H-8 will be equipped with
