The sensor’s sensitivity to salinity is interrogated by tracking the shift of the resonant wavelength. In Fig.5(b), the shift of one of resonances at around 1550 nm is plotted as a function of the molarity of the saline solutions. A total shift of 3.56 nm is obtained for the sa...

– Direct in-situ measurements of instrument dark offsets were necessary to accurately resolve backscattering at these low levels; – accurate pure seawater backscattering values are critical in determining particulate backscattering coefficients in the open ocean (not only in these very clear waters); ...
In Fig.4eand Supplementary Fig.S6a, the increase ofbbpappeared in the time intervals 09:00–15:00 and 21:00–00:00. The seawater temperature and salinity, measured every 2 h, were subtracted by their mean values at each depth to obtain their anomalies, as shown in Supplementary Fig.S6...
From a sensor perspective, uncooled complementary metal-oxide-semiconductor (CMOS) sensors, which feature high sensitivity and SNR, can be used in the VIS and NIR. Infrared-sensitive materials commonly used for SWIR and LWIR sensors include InGaAs, HgCdTe or InSbphotodiodes. A cooling system is ne...
In addition, these advanced sensing technologies can also be used for ocean salinity monitoring (Wang et al., 2016), seawater ion concentration monitoring (Wade et al., 2008), seawater pH value monitoring (Chiang et al., 2013), etc. Most pipeline defects and environmental loads are likely ...
An optical sensor for pH is described using a cross-linked network of bisilanes to immobilize a pH sensitive chromophore to a surface potentially exposed to a high pressure, high te
