The source and seasonality of rainfall in southern Arabia during the early‐ to mid‐Holocene and preceding humid periods are controversial because fossil lacustrine sediments provide solely indirect information on the amount of rainfall. Hydrogen and oxygen isotope measurements on fluid inclusion water trapped in Holocene and Pleistocene stalagmites from Hoti Cave in Northern Oman are direct indicators of the isotopic composition of paleoprecipitation. Isotope values of fluid inclusions formed during peak interglacial periods plot along monsoonal water lines and are indicative of a southern monsoonal moisture source. The last monsoon‐dominated period lasting from ∼10,100 to 6,300 years before present was terminated within a few decades in southeastern Arabia. The subsequent reduction in rainfall amount and change from predominantly summer to predominantly winter rainfall had a profound impact on human communities living in this area and triggered migration from inland to coastal areas where resources were more abundant.

“…Tropical cyclone rains have lower stable isotope ratios (Lawrence, & Gedzelman, 1996) probably due to the high, thick clouds, the large precipitation region and the precipitation longevity (Lawrence, Gedzelman, Zhang, & Arnold, 1998). Such stable isotope ratios decrease has been observed during typhoon in Japan (Fudeyasu et al, 2008), tropical cyclone in the Philippines (Jackisch et al, 2020) and in Oman (Müller, Friesen, Weise, Al Abri, Bait Said, & Michelsen, 2020). The period [1961][1962][1963][1964][1965][1966][1967][1968][1969][1970][1971][1972][1973][1974][1975] (Ivato station) has higher frequency of highly depleted precipitation than the period [2009][2010][2011][2012][2013][2014][2015][2016][2017][2018] (Ankatso station), which would have originated from tropical cyclone.…”

In the “Global Network of Isotopes in Precipitation” database, Antananarivo has two distinct datasets from two stations. Thirty-four years separate the two datasets. This study aims on the one hand to depict the variations of the water stable isotopes composition of precipitations from the two stations and understand their origins, mainly in relation to meteorological factors. On the other hand, the Antananarivo data are compared with regional and international data to identify other sources of isotope composition variability in precipitation. Isotope records showed that after thirty-four-year gap, summer and winter (the two main seasons) precipitations are more enriched in heavy isotopes. The precipitation amount fluctuation would mostly contribute to this temporal variation. Opposite to summer and winter precipitations, inter-season rainfalls have similar isotope values after thirty-four years. The two stations are geographically close and the spatial aspect is therefore negligible since there are no latitude nor altitude effects on the isotope composition of precipitations. Regarding the second order parameter d-excess, the monthly mean values from both stations are higher than 100/00 and could indicate moisture recycling. The comparison with regional/international data showed that the isotope variability in precipitation is primarily due to precipitation amount effect, different moisture source, the stations distance from it and the change of meteorological factors along the moisture trajectory.

Similarly, studies of the isotopic signatures of groundwater (Müller et al 2020) and freshwater molluscs (Lawrence 1998) have contributed to the palaeoclimatic dataset that largely depends on data from caves (Burns et al 1998(Burns et al , 2001Fleitmann et al 2004).…”

Exploring the Impact of Tropical Cyclones on Oman’s Maritime Cultural Heritage Through the Lens of Al-Baleed, Salalah (Dhofar Governorate)

Tropical cyclones are among the most detrimental hazards to the environment, societies, and economies, each year affecting millions of people and resulting in substantial casualties and material destructions in coastal communities. In this context, maritime cultural heritage, encompassing material evidence for the engagement of people with the sea, both on land and under water, is particularly vulnerable. Despite the significant number of archaeological sites exposed to tropical cyclones and other extreme sea-level events, maritime cultural heritage in the MENA region is rarely included in coastal vulnerability indices or incorporated in mitigation strategies, disaster management, sustainability, and resilience policies. In this study we examine the impact of tropical cyclones on the maritime archaeology of Oman with emphasis on the Dhofar region. This paper builds on existing coastal research in the Dhofar region—an area identified as the most cyclone-prone administrative region in Oman, but also an area that contains substantial archaeological remains. Central among Dhofar’s maritime cultural heritage is Al-Baleed, a Medieval seaport with unparalleled evidence of engagement with international trade networks.
