A floating mirror includes a buoyant body extending between a first end and a second end, and a reflective material disposed on opposite surfaces of the buoyant body.

A bathythermograph buoy and an associated method of operation are provided to measure temperature and/or optionally other parameter(s) within an ocean or another body of water. A bathythermograph buoy includes a housing and one or more sensors carried by the housing and configured to repeatedly measure one or more respective parameters as the bathythermograph buoy descends. The bathythermograph buoy of one example also includes a memory carried by the housing and configured to store representations of the one or more respective parameters measured by the one or more sensors. The bathythermograph buoy further includes a buoyancy modification device configured to increase buoyancy of the bathythermograph buoy to permit the bathythermograph buoy to ascend.

Disclosed herein are stackable cages for holding oysters, modular cages for holding oysters, floating platforms for deploying and retrieving oyster cages from a long line, and floats adapted to engage a plurality of oyster long lines and from which one or more oyster cages may depend.

Provided is an electricity generating module. The electricity generating module comprises: a cylinder; a piston that reciprocates inside the cylinder; and a power generating fiber of which one end is fixed to the piston and the other end is fixed to the cylinder, and of which the length varies according to the reciprocating of the piston, wherein, as the length of the power generating fiber varies, a potential value of the power generating fiber varies, and electricity is generated by using the varied potential value of the power generating fiber.

The present invention discloses an air-sea buoy monitoring system towards mid-latitude ocean including a meteorological data acquisition system, an underwater data acquisition system and a central processor. It collects data through different sensors via both meteorology and underwater data acquisition systems, and then transmits data to a central processor. The data collected by meteorology and underwater data acquisition systems will be analyzed and visualized via an information processing system and an image processing system. An alarm module is provided to alarm when meteorological data/value exceeds a certain threshold. This buoy monitoring system ensures the long term, continuous and simultaneous observation of multi-level/multi-factors for the air-sea interface and underwater oceanic environment at a fixed point, with the data being transmitted to shore-based data center in real time via communication satellites.

A container for housing and launching sonobuoy having a diverter and a casing divided into two portions by a cap. The container is configured to make a presence or an absence of the cap selective so as to be adapted to house and launch a single buoy of class A.

Systems and methods for deployment of ocean bottom seismic receivers into a body of water having a surface and a seabed. The system can include a remote operated vehicle (ROV) comprising a first wireless communication device. The system can include a seismic data receiver deployed on the seabed comprising a second wireless communication device. The first wireless communication device can be configured to communicate with the second wireless communication device. The ROV can move to a position adjacent to the seismic data receiver. The ROV can establish a wireless link with the seismic data receiver via the first communication device and second wireless communication device.
