HydrOCTOPUS : data from the EMSO-Azores observatory, 2016-2017

The HydrOctopus consists of 4 hydrophones connected to the same datalogger, to allow high-precision location of shallow events within the antenna.  The goal of the instrument is to study secondary (entrained) hydrothermal circulation associated with the highly active Tour Eiffel and Montségur vents of Lucky Strike volcano on the Mid-Atlantic Ridge.  Data are provided in miniSEED format, metadata in StationXML format. Network code is 4G.  Station codes are LSVHJ (2016-09 to 2017-07) and LSVHK (2017-07 to 2017-09).  Channel codes are all CDH and location codes are 01-04. The data and metadata can be processed using several seismological software suites, including (obspy’s filesystem.sds client)-[https://docs.obspy.org/packages/autogen/obspy.clients.filesystem.sds.Client.html#obspy.clients.filesystem.sds.Clien].  Important Note: This submission has been initially submitted to SEA scieNtific Open data Edition (SEANOE) publication service and received the recorded DOI. The metadata elements have been further processed (refined) in EMODnet Ingestion Service in order to conform with the Data Submission Service specifications.
