Shallow towed CTD (conductivity-temperature-depth) monitoring system for Arctic Ocean

Abstract

The invention relates to a shallow towed CTD (conductivity-temperature-depth) monitoring system for the Arctic Ocean. The shallow towed CTD monitoring system comprises an iced buoy device, an underwater profile detecting buoy device and a high-strength towed cable device, wherein the iced buoy device is applied to meteorological observation and control, satellite communication and power supply; the underwater profile detecting buoy device is used for carrying out buoyancy conversion and lifting control, and measuring the temperature, the salinity and the depth of seawater; and the high-strength towed cable device is used for connecting the iced buoy device and the underwater profile detecting buoy device, and providing a data signal wire, a high-strength towed cable and a seawater corrosion resistant vulcanized joint. According to the shallow towed CTD monitoring system for the Arctic Ocean, underwater CTD profile measurement can be carried out, the measurement depth is 0-120m below an ice layer, the blank of an international shallow observation method for 120m far from the sea is filled up, and synchronous hydrological and meteorological observation in the same region is achieved; an ultra-large capacity lithium battery power supply system is adopted, so that the service life of the system is prolonged; and the shallow towed CTD monitoring system has great popularization and application value, and can be popularized and applied to international related fields of polar region research.

Description

technical field [0001] The invention belongs to the application field of marine monitoring technology, and in particular relates to a towed-type temperature, salinity and depth monitoring system for shallow water in the Arctic Ocean. Background technique [0002] In recent years, the world's marine scientists have paid more and more attention to the characteristics of the Arctic and the Arctic Ocean marine environment and the impact of the Arctic ice and snow melting process on the climate. To engage in these researches, it is necessary first to obtain the data and changes of the temperature, salinity and depth of the Arctic and the Arctic Ocean marine environment, and to obtain these data requires corresponding observation and monitoring equipment. Meet the needs of Arctic scientific research. At present, the Woods Hole Oceanographic Institution in the United States has developed a "cable fixed-point deep-water profile monitoring system", which measures depths from 100 met...

To engage in these researches, it is necessary first to obtain the data and changes of the temperature, salinity and depth of the Arctic and the Arctic Ocean marine environment, and to obtain these data requires corresponding observation and monitoring equipment. Meeting the needs of Arctic scientific research

At present, the Woods Hole Oceanographic Institution in the United States has developed a "cable fixed-point deep-water profile monitoring system", which measures depths from 100 meters to 4,000 meters underwater, and is used for large-depth ocean profile monitoring. This device has two problems : First, the device itself has a battery, which can work continuously for a maximum of 3 months. Second, the marine environment shallower than 100° underwater cannot be measured, and it is precisely the changes and measurement data of the shallow sea environment in the Arctic Ocean that are most needed by marine scientists.
