An optical oxygen sensor and reaction vessel for high-pressure applications
Article Abstract:
Changes in oxygen concentration can be measured in aqueous or gaseous media using a simple hyperbaric chamber and optical oxygen probe. The optical detection method uses dynamic fluorescent quenching of a ruthenium metal complex. Initial experiments indicate that the sensor is rugged and well suited to function under high or variable pressures. The response time was under 10 s, temperature response was linear, with lower temperatures producing greater fluorescent quenching. The probe was not affected by pressures as high as 34.4 mPa (340 atm).

Storage of marine particulate samples for light-absorption measurements
Article Abstract:
Storage of marine particulate samples to be used for light-absorption measurements is discussed with liquid nitrogen temperatures found to b satisfactory. Optical properties in the ultraviolet region of the spectrum cannot be reliably assessed after samples are stored.
