AbstractOcean change leaves a potentially important imprint on ocean colorimetry. Here, we present an overview and current evaluation of the global ocean color variability from 1998 to 2022, and satellites observe that 36% of oceans (~122 million square kilometers, derived from valid observations) have experienced changes (P < 0.1).

This Letter proposes a novel, to the best of our knowledge, matrix digitization method for a photonic analog-to-digital converter with phase-shifted optical quantization (PSOQ-ADC). This method overcomes the issues of excessive bit width of the output code and the generation of invalid codes encountered by the traditional direct digitization method. A PSOQ-ADC was fabricated on a lithium niobate on insulator (LNOI) platform, and an experimental platform was built.

1. IntroductionThe Arctic is one of the regions most vulnerable to global climate change, as it experiences a warming rate approximately 1.5–4.5 times higher than the global average [1]. This is due to its unique environment, which amplifies the impacts of climate change [2]. The presence and changes in the primary environmental factors in the Arctic, such as ice and snow, have profoundly influenced the climate, hydrology, and ecology of the polar region, as well as the global environment.
