At Sea-Bird Scientific, we are committed to enabling the science that matters. The Deep SeapHOx V2 moored system is a testament to our dedication to providing tools that withstand the harshest ocean conditions and deliver meticulously accurate data. Whether you’re studying ocean acidification or monitoring deep-sea ecosystems, the Deep SeapHOx V2 is your reliable partner in oceanographic research. While called a ‘Deep’ system, the Deep SeapHOx V2 can be moored just below the sea-surface and through the water column down to 2,000 meters, making it a perfect solution for any application from shallow to deep ocean.

Deep SeapHOx V2 Key Features

• Comprehensive Monitoring – The Deep SeapHOx V2 combines pH, conductivity, temperature, pressure, and optical dissolved oxygen measurements in one robust package
• Extended Deployment – With a solid-state ion selective field effect transistor (ISFET) adapted for low to high-pressure environments, the Deep SeapHOx V2 ensures stability and high-quality data for at least one year, reducing field servicing costs and data gaps.
• Versatile Applications – Ideal for ocean acidification research, climate studies, marine biology, carbon cycle analysis, deoxygenation monitoring, deep-sea coral research, fisheries and aquaculture, and food web studies.
• User-Friendly Design – Features an integrated pump, RS-232 interface, internal memory with optional real-time output, and batteries, with the option for external power. The unique flow path and anti-fouling technology extend deployment durations and protect against biofouling.

Applications and Case Studies

The Deep SeapHOx V2 is designed to support a wide range of oceanographic research and monitoring applications:

• Carbon cycle analysis – track the movement and storage of carbon in the ocean to better understand the global carbon cycle.
• Climate science – collect data on ocean temperature and salinity to contribute to climate models and predict future climate change scenarios.
• Coral reef monitoring – investigate the conditions that support deep-sea coral ecosystems and assess their vulnerability to environmental changes.
• Deoxygenation and hypoxia monitoring – measure dissolved oxygen levels to identify and study hypoxic zones, which can have significant impacts on marine life.
• Fisheries and aquaculture – early warning and monitoring for critical marine resources that are sensitive to changing pH.
  • Case study – Experimental kelp farming with Saccharina latissima

• Food web studies – analyze the interactions between different species in the marine food web and how they are affected by environmental factors.
• Marine biology – Study the health and behavior of marine organisms in response to changing environmental conditions.
• Ocean acidification – monitor changes in ocean pH levels to understand the impacts of increased carbon dioxide on marine ecosystems.
  • Case study – Inductive modem technology for use in measuring pH
