“…We now demonstrate the utility of the compensation methods described above to the salinity measurement. Salinity measurements are important in many areas of environmental and marine science such as global warming, − ecological variations, − and biotic activities. − The refractive index of seawater changes by Δ n ≈ 2 × 10 –3 /% salinity, so the demonstrated sensitivity of a GMR sensor in the low 10 –5 range allows the determination of salinity with high accuracy. Salinity measurements are typically conducted in the field and involve mechanical vibrations and temperature fluctuations; hence, salinity measurements are ideally suited to showcasing the benefit of the compensation methods introduced here.…”

Resonant photonic refractive index sensors have made major advances based on their high sensitivity and contact-less readout capability, which is advantageous in many areas of science and technology. A major issue for the technological implementation of such sensors is their response to external influences, such as vibrations and temperature variations; the more sensitive a sensor, the more susceptible it also becomes to external influences. Here, we introduce a novel bowtieshaped sensor that is highly responsive to refractive index variations while compensating for temperature changes and mechanical (linear and angular) vibrations. We exemplify its capability by demonstrating the detection of salinity to a precision of 0.1%, corresponding to 2.3 × 10 −4 refractive index units in the presence of temperature fluctuations and mechanical vibrations. As a second exemplar, we detected bacteria growth in a pilot industrial environment. Our results demonstrate that it is possible to translate high sensitivity resonant photonic refractive index sensors into real-world environments.

“…The diversity of micro and macroborers in intertidal and shallow sublittoral environments is usually quite high . Molluscan shells can provide the only hard substrate available for larval settlement and ontogeny development by different types of boring and encrusting organisms in soft-bottom areas (Parras and Casadío, 2006;Lopes, 2011;El-Sorogy, 2015;El-Sorogy et al, 2018). Based on the reduction or lack of sedimentation, rocky shorelines offer exceptional conditions for colonization by boring and encrusting organisms (Santos et al, 2011).…”

Herein, 20 ichnospecies belonging to 8 ichnogenera were identified in bivalves, gastropods, and corals (n = 701) from the Late Pleistocene coral reef along the Red Sea coast, northwest Saudi Arabia. The trace fossils were produced by clionid sponges (47.39%), endolithic bivalves (42.17%), polychaete annelids (5.42%), vermetid gastropods (3.81%), and acrothoracican barnacles (1.21%). The recognized ichnotaxa were Entobia geometrica, E. ovula, E. cf. goniodes, E. cf. retiformis, E. cretacea, Entobia isp., Gastrochaenolites torpedo, G. lapidicus, G. cf. dijugus, Gastrochaenolites isp., Oichnus paraboloides, O. simplex, Oichnus isp., Caulostrepsis taeniola, Caulostrepsis isp., Maeandropolydora cf. sulcans, Maeandropolydora isp., Renichnus isp., Centrichnus isp., and cf. Rogerella isp., Most bivalves and gastropods contain Entobia rather than Gastrochaenolites, which is commonly found in the larger and thicker corals. The content of the trace fossils indicated an Entobia ichnofacies formed in the coral reef during transgression. The habitat conditions changed gradually, from well-oxygenated, shallow, high-energy back-reef and reef crest bioeroding polychaetes and bivalves, to deep, low-energy reef slope dominated by boring sponges.
