劳盆地南部的valu Fa Ridge （VFR）位于向西倾斜的Tonga-Kerrnadec俯冲带的后面，是西南太平洋最早探索热液活动的目标之一（图1）。1989年，法德潜水项目NAUTILAU （Nautile-lan）在该地区发现了活跃的热液田，喷出高温高酸度流体，并伴有大量矿床[Fbuquet et al., 1993]。2004年9 - 10月，“太平洋西南缘热液喷口”（SWEEP）考察队利用“新海6500”深海潜水研究船（DSRV）对VFR的热液系统进行了探测和采样。2004年的新海潜水集中在Valu Fa Ridge深海热液喷口生态系统的地球生物学和地球化学特征上，并在他们发现15年后对这些热液区有了新的认识。2004年的潜水是第一次重新审视这一地区，随后有进一步的潜水计划和持续的研究。
TheValu Fa Ridge (VFR) in the southern Lau Basin—located behind the westward-dipping Tonga-Kerrnadec subduction zone—was one of the earliest targets to b e explored for hydrothermal activity in the southwestern Pacific Ocean (Figure l).In 1989, the French-German dive program NAUTILAU (Nautile-lan) discovered active hydrothermal fields venting high-temperature fluids with high acidity accompanied by massive ore deposits in this area [Fbuquet et al., 1993]. In September–October 2004, the SWEEP VENTS (Southwestern Edge of Pacific hydrothermal vents) expedition explored and sampled the hydrothermal systems of the VFR using the deep submergence research vehicle (DSRV) Shinkai 6500. The 2004 Shinkai dives focused on the geobiological and geochemical character of the deep-sea hydrothermal vent ecosystems of the Valu Fa Ridge and shed new light on these hydrothermal fields 15 years after their discovery These 2004 dives were the first to revisit this area, and have been followed by further dive programs and continued research.
