“…It is hard to say without independent verification which of the calculations is closer to the true value. At least for Yeoja Bay, an independent residence time from hydro-dynamic modeling exists of 16 days [36]. This is double the Hwang et al [27] estimate and is about a third of the Project Open RaDOM estimate.…”

Radium has been commonly used as a tracer of submarine groundwater discharge to the ocean and embankments, as radium activities are commonly input into box models to calculate a groundwater flux. Similarly, isotopes of radium (Ra224, Ra223, Ra226, Ra228) have been used to calculate water mass ages, which have been used as a proxy for residence times. Less commonly, radium and other tracers have been utilized in mixing models to determine the relative contribution of groundwater to a marine system. In the literature, all of these methods have almost exclusively been solved using analytical methods prone to large errors and other issues. Project Open RaDOM, introduced here, is a collection of open-source R scripts that numerically solve for groundwater flux, residence time, and relative contribution of groundwater to coastal systems. Solving these models numerically allows for over-constrained systems to increase their accuracy and force real solutions. The scripts are written in a way to make them user-friendly, even to scientists unfamiliar with R. This communication includes a description of the scripts in Project Open RaDOM, a discussion of examples in the literature, and case studies of the scripts using previously published data.

“…Therefore, the Sihwa and the Saemangeum reclamation project was the catalyst for researchers to study about the environmental value of tidal flat in depth. There are several papers dealing with the environmental importance of coastal areas or tidal flats using scientific data (See Lee et al 2008;Ryu et al 2011;Chang et al 2012;Hong 2012). The results from our paper could be useful economic information concerning the Korean tidal flat to be used in the process of policy-making and conservation management plans.…”

Tidal flats are well known as highly productive areas that support the ecosystem by providing essential nutrients. However, they have been increasingly reclaimed as sites for factories or farms in Korea. Recently, an increasing number of Koreans have been calling for the conservation of tidal flats, with the demand that they be designated as protected areas. Thus, policy-makers and the public require monetary information on the conservation value of tidal flats. This paper attempts to assess the conservation value of tidal flats in Shinan, Korea, by using the contingent valuation (CV) method. A CV survey of Korean households was conducted to estimate their willingness to pay (WTP) for the conservation of the Shinan Tidal Flat and the avoidance of its development. In general, the respondents accepted the contingent market, and on average, Korean households were willing to pay a significant amount. The mean WTP for the conservation of the Shinan Tidal Flat was estimated to be approximately KRW 3100 (USD 2.75) per year per household. This implies that Korean households may be willing to pay a total of approximately KRW 54.5 billion (USD 48.3 million) annually for 5 years. The results can be used in the decision-making process of policy-makers about the conservation of the Shinan Tidal Flat.

We compiled and analyzed long-term time-series data collected in Korea to evaluate changes in oceanographic conditions and marine ecosystems near Jeju Island (33 o 00'-34 o 00' N, 125 o 30'-127 o 30' E) from 1981 to 2010. Environmental data included depth-specific time series of temperature and salinity that have been measured bimonthly since 1961 in water columns at 175 fixed stations along 22 oceanographic lines in Korean waters by the National Fisheries Research & Development Institute, and time series of estimated volume transport of the Tsushima Warm Current (TWC) and Korea Strait Bottom Cold Water (KSBCW) for the period from 1961 to 2008. We analyzed the species composition in terms of biomass of fish species caught by Korean fishing vessels in the waters near Jeju Island (1981-2010). Data were summarized and related to environmental changes using canonical correspondence analysis (CCA).
