during the summers of 2008 and 2009 revealed that both air and surface seawater partial pressures of CO 2 (pCO 2 ) showed regular diurnal cycles. Minimum values occurred in the evening and maximum values in the morning. Air pCO 2 in each of the three study areas showed small diurnal variations, while large diurnal variations were observed in seawater pCO 2 . The diurnal variation amplitude of seawater pCO 2 was ~70 μmol mol -1 at the Yongshu Reef lagoon, 420-619 μmol mol -1 on the Yongxing Island reef flat, and 264-579 μmol mol -1 on the reef flat of the Luhuitou Fringing Reef, and 324-492 μmol mol -1 in an adjacent area just outside of this fringing reef. With respect to spatial relations, there were large differences in air-sea CO 2 flux across the South China Sea (e.g. ~0.4 mmol CO 2 m -2 d -1 at Yongshu Reef, ~4.7 mmol CO 2 m -2 d -1 at Yongxing Island, and ~9.8 mmol CO 2 m -2 d -1 at Luhuitou Fringing Reef). However, these positive values suggest that coral reef ecosystems of the SCS may be a net source of CO 2 to the atmosphere. Additional analyses indicated that diurnal variations of surface seawater pCO 2 in the shallow water reef flat are controlled mainly by biological metabolic processes, while those of deeper water lagoons and outer reef areas are regulated by both biological metabolism and hydrodynamic factors. Unlike the open ocean, inorganic metabolism plays a significant role in influencing seawater pCO 2 variations in coral reef ecosystems. coral reefs, pCO 2 , carbon cycle, summer, South China Sea Citation:

“…The frequency and magnitude of extreme wave events such as those generated by tropical cyclones and tsunamis can be recorded directly in the form of transported blocks and storm ridges and ramparts, and less directly in the records preserved in lagoonal, coastal and swamp sediments, tree rings and speleothems (Bryant and Nott, 2001;Nott and Hayne, 2001;Nott, 2003;Yu et al, 2004Yu et al, , 2009Miller et al, 2006;Nott et al, 2007).

“…Yu et al (2004) used the TIMS U-Th method to date wave-transported coral blocks on Yongshu Reef in the South China Sea. Detailed field investigations of coral reef geomorphology, geology and ecology led them to conclude that these blocks had been transported from sites on the reef front living-coral zone by high-magnitude storms or tsunamis.…”

“…Since that time, the method has been successfully applied to dating a variety of young carbonate deposits. The results have been employed in high-resolution climatic reconstruction (Denniston et al, 2000;Cobb et al, 2003a;Yuan et al, 2004;Wang et al, 2005;Hu et al, 2008;Lorrey et al, 2008), in the assessment of co-seismic uplift rates and earthquake recurrence intervals (Edwards et al, 1988;Zachariasen et al, 1999), in the characterisation of historical storm events (Yu et al, 2004(Yu et al, , 2006aZhao et al, 2009), to establish the timing of episodes of recent coral mortality (Yu et al, 2006b) and in the investigation of settlement patterns in Hawaiian prehistory (Kirch and Sharp, 2005;Weisler et al, 2006). Despite this range of applications, the use of this high-resolution dating technique is still restricted and its potential has not been widely recognised.…”

Catastrophic events often interrupt long‐term Earth surface processes. In coastal areas, although millennial‐scale trends of climatic and sea‐level changes determine the trajectory of sedimentary landform evolution, storm and/or tsunami activity can cause abrupt changes in depositional conditions that may alter the long‐term sedimentary processes. Here, we report a sedimentary hiatus that is widely observed from the late Holocene sedimentary sequence at the seabed along the southeast China coast. This hiatus was discovered by close temporal sedimentary and radiocarbon dating analyses of a seabed sedimentary sequence in the mouth area of the Pearl River estuary. The results suggest that a couple of metres in the middle to late Holocene sediment at the seabed were eroded by a catastrophic event happening c. 1000–800 cal. Years BP. In theory, a mega‐tsunami generated from the Manila Trench could have caused such erosion at the seabed, but there is a lack of direct geological and historical evidence to support such a hypothesis. Much more likely, a super‐typhoon struck the coast and caused the erosion. This hypothesis is strongly supported by the region's historical and geological records, which suggest a period characteristic of intense typhoons ranging from the Medieval Warm Period to the climate transition phase (c. 1000–600 cal. Years BP). During the subsequent Little Ice Age, deposition of sandy sediment continued, suggesting frequent but weaker typhoon activity. Over the past two centuries the deposition of sandy sediment and gravels began, implying the beginning of a phase of intensifying typhoon conditions, possibly a result of the recent warming climate. © 2020 John Wiley & Sons, Ltd.
