Standard profiling floats

STANDARD PROFILING FLOATS | BIO & SPECIFIC PROFILING FLOATS | HIGH & LOW DEPTH PROFILING FLOATS

NKE Instrumentation is involved in the international ARGO program in order to supply profiling floats measuring temperature and salinity. Therefore one of the company’s key activities is the development of these floats in order to support the scientific community, notably in partnership with IFREMER. The so-called “standard” profiling floats are the ARVOR and PROVOR ranges, which communicate by ARGOS or Iridium transmission the CTD data collected autonomously during acquisition periods. These profiling floats can also be fitted with other sensors including a dissolved oxygen sensor.

ARVOR L: TS, 2000m

ARVOR L: TS, 2000m

Description - ARVOR L provides salinity, temperature and pressure profiles up to 2000 meters depth. Data and positioning are achieved ARGOS satellites.

Mission with two depth values alternated and grounding avoidance function are settable by user before mission.

With self-ballast and very light design, ARVOR L can be deployed by one person.

It capitalizes on both the know-how of Ifremer in floats activities and designing qualified subassemblies and of nke on industrial product development.

ARVOR I: TS, 2000m, Iridium

ARVOR I: TS, 2000m, Iridium

Description - ARVOR I provides salinity, temperature and pressure profiles with position information thanks to an integrated GPS receiver. Data are transmitted via Iridium satellites network.

Bluetooth technology enables easy and fast configuration before mission. Iridium downlink enables parameters modification remotely as soon as the ARVOR I surfaces.

With self-ballast and very light design, ARVOR I can be deployed by one person.

It capitalises on both the know-how of Ifremer in floats activities and designing qualified subassemblies; and of NKE on industrial product development.

PROVOR CTS3: TS, 2000m, Argos

PROVOR CTS3: TS, 2000m, Argos

Description - PROVOR CTS3 is a reliable, cost-effective float with self-ballast that collects typically 112 data triplets (salinity, temperature and pressure) during its drifting and ascending phases. Once at the surface, these data are sent via the ARGOS system. The PROVOR CTS3 is designed to achieve up to 250 cycles.

More than 700 units have been produced since 1998.

PROVOR CTS3 can be launched from any vessel at slow speed using only a rope and at high speed (20 knots checked) by using release kit and launching crate. The PROVOR has been developed in industrial partnership with Ifremer.

PROVOR I: TS, 2000m, Iridium

PROVOR I: TS, 2000m, Iridium

Description - PROVOR I is an efficient and reliable autonomous profiling float designed to acquire CTD profiles from 2000 meters to the surface.

PROVOR I has been matched for long mission duration and high resolution profile: up to 300 cycles or up to 2000 CTD points the profile.

PROVOR I is proposed with GPS receiver and transmission through IRIDIUM constellation by using SBD or RUDICS mode. The two ways communication system enables: data and positioning collection, remote control facilities. Firmware is designed to transmit in shifted mode non transmitted profiles.

PROVOR CTS3 DO: TS, DO, 2000m, Argos2

PROVOR CTS3 DO: TS, DO, 2000m, Argos2

Description - PROVOR CTS3 DO is efficient and reliable autonomous profiling floats designed to acquire CTD and Dissolved oxygen profiles: from 2000 m to the surface.

Once at the surface, data are sent via satellite and a new cycle begins.

The PROVOR DO is proposed with transmission by ARGOS that is one way data collection and positioning by satellites. The PROVOR is a cost-effective float with hydraulic feature enabling a deployment anywhere in the ocean without preballasting: this enables to simplify deployments.

It has been developed in industrial partnership with Ifremer.
