The Benthic Ichthyofauna Net for Coral/Kelp Environments (BINCKE) is a rectangular net opened and closed by means of a rigid, hinged frame at one end and of variable size depending upon the size and behavior of targeted species. It is used for the collection of fishes from structurally complex environments (e.g., coral reefs, kelp forests.

A device that collects samples of pore water from various horizons below the seabed.

Beardsley Drifters are near-surface satellite-tracked drifters used for observations of circulation patterns. They are WOCE-style drifters featuring holey sock drogues. Each drifter has a small (~ 30 cm diameter) surface float with ARGOS transmitter and batteries tethered to a holey sock drogue centered at 15 m below the surface. The drogue, about 10 m tall and 1 m in diameter, is designed to "lock" itself to the water so that the surface float follows the mean water motion at 15 m depth with very little slippage even in high winds. Thus measuring the drifter's position as a function of time provides a Lagrangian measurement of the 15-m ocean current.

A high-speed imaging camera is capable of recording rapid phenomena with high-frame rates. After recording, the images stored on the medium can be played back in slow motion. The functionality in a high-speed imaging device results from the frame rate, or the number of individual stills recorded in the period of one second (fps). Common video cameras will typically record about 24 to 40 fps, yet even low-end high-speed cameras will record 1,000 fps.

A long-range current profiler designed for combined current profile and biomass measurements. The Signature100 combines a four-beam current profiler operating at 100 kHz with an optional scientific echosounder. Applications include providing insight into the dynamics of zooplankton, krill or schools of fish; current profiling; providing insight into small-scale physical processes; and upwelling and downwelling studies. The instrument is suitable for buoy mounting with internal attitude and heading reference system (AHRS). Optional centre beam with 70-120 kHz Both the current profiler and the biomass measurements have an effective range of 300-400 m. The echosounder has a velocity resolution of 0.1 cm/s, a maximum sampling rate of 1 Hz (1/2 Hz at max output power), and a standard range of 0-1500 m.

A device that is used for the vacuum-driven processing of multiwell strips or plates, or spin columns.

A portable analyzer designed for laboratories or field based isotope analysis. It uses Cavity Ring-Down Spectroscopy (CRDS) to measure the spectral signature of the molecule of interest. The instrument includes a closed-loop temperature and pressure control. The L1102-i can be used for analysis of liquid water only. It has a typical precision of 0.1 per mil for d18O and 0.5 per mil for dD.

A caliper (or "pair of calipers") is a device used to measure the distance between two opposite sides of an object. Many types of calipers permit reading out a measurement on a ruled scale, a dial, or a digital display.

A square or rectangular rigid frame of known area, often home-made, that is placed on the substrate to be sampled to mark a fixed area for sampling flora or fauna.

Particle size analysis, particle size measurement, or simply particle sizing is the collective name of the technical procedures, or laboratory techniques which determines the size range, and/or the average, or mean size of the particles in a powder or liquid sample.

In-situ instruments that can determine the proportion of one or more gaseous components of the atmosphere.

Fukui produces multi-species, multi-purpose collapsible or stackable fish traps, available in different sizes.

Capable of being performed in numerous environments, push coring is just as it sounds. Push coring is simply pushing the core barrel (often an aluminum or polycarbonate tube) into the sediment by hand. A push core is useful in that it causes very little disturbance to the more delicate upper layers of a sub-aqueous sediment.

A hydrophone is a microphone designed to be used underwater for recording or listening to underwater sound. Most hydrophones are based on a piezoelectric transducer that generates electricity when subjected to a pressure change.

A gas generator that generates hydrogen gas.

The Chromium Controller by 10x Genomics uses advanced microfluidics to perform single-cell partitioning and barcoding. Powered by Next GEM technology, the Chromium Controller enables integrated analysis of single cells at massive scale. Chromium Single Cell products can capture molecular readouts of cell activity in multiple dimensions, including gene expression, cell surface proteins, immune clonotype, antigen specificity, and chromatin accessibility.

A thermistor is a type of resistor whose resistance varies significantly with temperature, more so than in standard resistors. The word is a portmanteau of thermal and resistor. Thermistors are widely used as inrush current limiters, temperature sensors, self-resetting overcurrent protectors, and self-regulating heating elements.

Thermistors differ from resistance temperature detectors (RTD) in that the material used in a thermistor is generally a ceramic or polymer, while RTDs use pure metals. The temperature response is also different; RTDs are useful over larger temperature ranges, while thermistors typically achieve a higher precision within a limited temperature range, typically 90C to 130C.

An enclosed chamber designed to produce heat.

A system of instruments/devices that provide irradiation of materials. Irradiation is an energy transfer process during which a material entity receives energy through radiation.

The Paroscientific 410K Pressure Transducer is an absolute pressure transducer with a Digiquartz pressure sensor and precision thermometer. Operates over a temperature range of 0-125 degC and a pressure range of 0-10000 psia with a typical accuracy of 0.01% and a resolution of 0.0001%.

Instruments that generate enlarged images of samples using the phenomena of fluorescence and phosphorescence instead of, or in addition to, reflection and absorption of visible light. Includes conventional and inverted instruments.

An immersion transducer is a single element longitudinal wave transducer with a 1/4 wavelength layer acoustically matched to water. Immersion transducers are specifically designed to transmit ultrasound in applications where the test parts are partially or wholly immersed in water, which allows a uniform and fast coupling technique for rapid scanning of parts.

A muffle furnace or muffle oven (sometimes retort furnace in historical usage) is a furnace in which the subject material is isolated from the fuel and all of the products of combustion, including gases and flying ash.  A type of jacketed enclosure that is used to heat a material to significantly high temperatures while keeping it contained and fully isolated from external contaminants, chemicals or substances. Muffle furnaces are usually lined with stainless steel, making them largely corrosion-resistant.

The PME miniDOT logger is a submersible sensor designed to measure water temperature and dissolved oxygen concentration. Dissolved oxygen is measured by an optode that measures lifetime-based luminescence quenching of a thin membrane. The sensing foil contains a coating with a variable fluorescence depending on the oxygen concentration of the surrounding water. The miniDOT reports in milligrams per liter (mg/L) and logs all measurements to an internal SD card. Also featured is a temperature sensor and batteries. Data can be offloaded to a computer via USB cable. The logger has an accuracy of +/- 5 percent (+/- 0.3 mg/L) for oxygen, and +/- 0.1 degrees Celsius for temperature. Temperature range is 0 to 35 degrees Celsius, oxygen range is 0 to 150 percent saturation. Depth-rated to 300 meters.
