Embedding all the necessary requirements, an expendable conductivity, temperature and depth system is developed for oceanography measurements. It can be freely dropped by hand from any ships without environmental interventions also and data is collected, transferred using wireless communication technology. The data can be collected either in descending or ascending operation which is being implemented using positive and negative buoyancy methodology. The WXCTD is a system used to measure and store the CTD data in real time upon surfacing in Ocean
