Deep-ocean tides in the South-West Indian Ocean: comparing deep-sea pressure to satellite data

Deep ocean pressure measurements in two regions of the South-West Indian Ocean (West and East of Madagascar), covering one to two years of data, are analysed for tidal motions. The pressure data are taken both from Bottom Pressure Recorders as well as from mid-water column instruments. Coherent tides are characterised by fixed amplitudes and phases. Those inferred from bottom measurements compare well to tides obtained from satellite altimetry, and cover up to 99% of the pressure variance in the frequency band having periods shorter than 29 hours. Long-period tides, in the low-frequency band, are regularly overshadowed by (unwanted) eddy-induced mooring motion (‘blow-down’), which events have therefore been eliminated. In the Mozambique Channel, semidiurnal surface tides are stronger than East of Madagascar, and all appear to be near resonance with a basin mode. Away from the bottom, coherent internal tides were determined. Evidence of the presence of incoherent internal tides has been obtained by applying Harmonic Analyses over a moving time window of 1 year duration. East of Madagascar internal tides appear to be very strong, although its source remains unclear

CTD/LADCP-data in the western part of the Romanche Fracture Zone in 2011-2014

The data set contains the processed CTD / LADCP data of 25 hydrographic stations performed in the western part of the equatorial Romanche Fracture Zone in 2011-2014 from the R/V "Akademik Sergey Vavilov". The processing of the raw data was carried out by standard processing packages SBE Data Processing and the LADCP Processing, version IX.8. The temperature and salinity data are given with an interval of 2 db. The LADCP data are given with an interval of 8 or 16 m. The files of the LADCP processing protocols and the figures generated by processing package are given

Simulation of discrete-continuous process via E-network

This paper denotes approaches to discrete-continuous process simulation via E-network. It covers principals of discrete-continuous process simulation via E-networks using the scheme of the interaction of static and dynamic components modeling. The construction of discrete-continuous process dynamic models is based on the state space method and is implemented by using E-network
