  abstract = {{W}e describe a novel compact autonomous in situ sensor for semi-continuous measurement of water isotopes (delta {D}, delta 18{O}, and delta 17{O}) in liquid water. {T}he sensor relies on a dual-inlet water vapor injection system based on the pervaporation through a semi-permeable membrane, and on the water vapor composition analysis using a dedicated optical feedback cavity enhanced absorption spectrometer. {T}he sensor has dimensions of 165 mm diameter and 550 mm long, for a weight of similar to 8 kg. {A} titanium casing allows applications down to 6000 m deep for a total effective weight of 45 (23) kg in air (water). {I}t has a power consumption of similar to 40 {W}, and an autonomy of 10-12 h which is ensured by a dedicated {L}i-ion battery pack. {T}he sensor is equipped with single-pair high-speed digital subscriber line communication for telemetry purposes. {T}he instrument provides an accuracy of 0.3 parts per thousand (2 sigma) for all water isotopes with a 9-min integration time. {T}he instrument is suitable for investigating the freshwater cycle in the ocean, and in particular the transformation of ocean water masses related to iceberg and ice shelf melting.},
