The Sea-Bird SBE 41/41CP Argo CTD module was developed in response to the scientific need for highly stable and accurate temperature and salinity on profiling floats. The standard CTD for Argo floats, the SBE 41/41CP have helped provide an unprecedented amount of data since the creation of the Argo program. WebApr 1, 2024 · Abstract Sea-Bird Scientific SBE 41CP CTDs are used on autonomous floats in the global Argo ocean observing program to measure the temperature and salinity of the upper ocean. While profiling, the sensors are subject to dynamic errors as they profile through vertical gradients. Applying dynamic corrections to the temperature and … WebThe SBE-41 operates in the spot-sampling mode only and collects discrete samples according to a pre-set pressure table, with the CTD pump turned off between samples. The SBE-41CP has the capability to operate in both the spot-sampling mode and the continuous-profiling (CP) mode. town clerk carlisle ma

WebThe Sea-Bird SBE-41 and 41CP CTDs were equipped with Paine pressure sensors until early 2000. The Paine sensors exhibit a positive drift with time but less than +10 dbars over the life of a float. The sensors also exhibit a span change (slope in pressure calibration) that has a magnitude of about 10% of the offset drift.
