The Lamont Doherty ocean-bottom seismometer fleet, a part of the US national ocean bottom seismometer instrument pool, will reach 60 instruments by early 2003. This funding provides for upgrades for the 21 aging, first generation instruments designed in 1986. These upgrades will make the new and old instruments identical in performance and data format. These upgrades will improve reliability, increase the dynamic range, covert the instruments to PASSCAL standard sampling rates, replace faulty older generation releases, add radio and strobe recovery aids, and replace broad band hydrophone systems with hybrid differential pressure gauge/hydrophone pressure sensors.

拉蒙多尔蒂海底地震仪队是美国国家海底地震仪仪器库的一部分，到2003年初将达到60台仪器。 这笔资金用于升级1986年设计的21台老化的第一代仪器。 这些升级将使新老仪器在性能和数据格式上完全相同。这些升级将提高可靠性，增加动态范围，将仪器转换为PASSCAL标准采样率，更换有故障的老一代版本，增加无线电和选通恢复辅助设备，并将宽带水听器系统更换为混合差压计/水听器压力传感器。
