“…Near Vancouver, Canada, the pandemic-induced reduction in commercial shipping traffic resulted in 1.5-2.7 dB reductions in underwater noise in the 100 Hz band at three out of four hydrophone stations in the first 3 months of 2020, whereas the fourth hydrophone showed no difference in sound levels (Thomson and Barclay, 2020). Not all human activities or sectors of the maritime industry were equally affected during the pandemic (Ito et al, 2020;Millefiori et al, 2020;Yazir et al, 2020;Notteboom et al, 2021). In the Mediterranean, for example, decreases in shipping occurred more in coastal areas and lasted longer in sectors other than cargo and tanker shipping (March et al, 2020).…”

The global COVID-19 pandemic caused a sharp decline in vessel traffic in many areas around the world, including vessel-based tourism throughout Alaska, USA in 2020. Marine vessel traffic has long been known to affect the underwater acoustic environment with direct and indirect effects on marine ecological processes. Glacier Bay National Park in southeastern Alaska has monitored underwater sound since 2000. We used continuous, calibrated hydrophone recordings to examine 2020 ambient sound levels compared with previous years: 2018, the most recent year with data available, and 2016 for historical perspective. Park tourism occurs mainly in May–September. Overall, the number of vessel entries in Glacier Bay was 44–49% lower in 2020 (2020: n = 1,831; 2018: n = 3,599; 2016: n = 3,212) affecting all vessel classes, including the complete absence of cruise ships and only three tour vessel trips. In all years, we found clear seasonal and diurnal patterns in vessel generated noise, focused from 06:00 to 20:00 local time (LT) in the summer months. Broadband (17.8–8,910 Hz) sound levels in the 2020 Visitor Season were 2.7 dB lower than 2018 and 2.5 dB lower than 2016. Focusing on morning (06:00–09:00 LT) and afternoon (15:00–18:00 LT) time-blocks when tour vessels and cruise ships enter and exit Glacier Bay, median broadband sound levels were 3.3–5.1 dB lower in 2020 than prior years. At the 95th percentile levels, morning and afternoon peak times in 2020 were 6.3–9.0 dB quieter than previous years. A 3 dB decline in median sound level in the 125 Hz one-third octave band in 2020 reflects a change in medium and large vessel noise energy and/or harbor seal vocalizations. Our results suggest that all types of vessels had a role in the quieter underwater sound environment in 2020, with the combined acoustic footprint of tour vessels and cruise ships most evident in the decrease in the 95th percentile loudest sounds. This and other descriptions of the pandemic-induced quiet, and the gradual return to increased activity, can help inform efforts to improve existing methods to mitigate vessel noise impacts and maintain the ecological integrity of marine protected areas.

“…It has been observed that one of the major routes that are generally used for transportation is the ocean routes that the firms can use in different countries for dealing with the supply chain activities based on the assessment of Gray (2020). It has also been discussed that there have been different changes related to ocean freight worldwide due to the COVID-19 pandemic that has created constraints for the countries for carrying out the means of transportation (Yazir et al, 2020).…”

Recent research has shown that the COVID-19 pandemic has holistically affected the financial and industrial sectors of China, in a considerably adverse manner. This paper aims to examine the impact of the COVID-19 virus on the transportation and logistics sector in China. In this regard, the study opted for a quantitative method of research design, along with primary data collection. The explanatory variable here is the COVID-19 virus, whereas, the dependent variables are air freight, ocean freight, and land freight. The data analysis technique used is the Structural Equation Modelling (SEM) analysis, comprising of the Confirmatory Factor Analysis (CFA) and the path assessment method. A structured survey questionnaire was also used, and the survey questionnaire scale was set from strongly agree to disagree strongly. The findings revealed that the effect of COVID-19 on air freight is statistically negative and significant. Moreover, the impact of COVID-19 on land freight is statistically negative and significant, whereas the effect of COVID-19 is statistically insignificant in the context of ocean freight, particularly during the period of the COVID-19 pandemic. Therefore, keeping these results in consideration, policymakers can enhance their support, so as to increase the performance of the logistics and transportation sector in China.

“…Besides, there are much broader possibilities to use information technologies in counteracting the challenges of the COVID-19 pandemic. For example, it is believed that effective Port State Inspections based on IMO conventions and big data applications could reduce potential operation risk and provide successful turnaround opportunities (Yazir et al, 2020). Besides, development of the information management in the field including above mentioned digital solutions should not be viewed as a temporary measure, rather as a new regime that very likely may become a business of usual.…”
