“…The survey was carried out on July [18][19][20]2011. To make the analysis more convenient, the survey was divided into two sections: via the estuary of the Artemovka R. (stations 1-5, 15, 17-19) and via the estuary of the Shkotovka R. (stations [6][7][8][9][10][11][12][13][14][15][16]. In this case, according to a definition given in [28] and amended in [16], by estuary is meant to be the entire examined water area, except for the stations in most remote riverine parts of the area (stations in and 6), which were not reached by seawater during the study.…”

Production-destruction processes in estuaries of the rivers of Artemovka and Shkotovka (Usuri Bay) in summer

et al. 2015

Production and hydrochemical characteristics of the estuaries of the rivers of Artemovka and Shkotovka, flowing into the apex of the Ussuri Bay (the Sea of Japan), were studied in the summer of 2011. Because of the high rate of destruction processes, the partial pressure in river waters of the Shkotovka, Arte movka, and Knevichanka (the Artemovka's major tributary) was 800, 1800, and 3700 µatm, respectively. Unlike the Shkotovka R. estuary, the high trophic level of the Artemovka R. and a favorable combination of hydrological and hydrochemical conditions in the study period determined the high rate of production pro cesses (chlorophyll a concentration reached 200 µg/L, oxygen oversaturation was more than twofold, the par tial pressure of carbon dioxide dropped to 25 µatm). A conservative and nonconservative dependence of alka linity on salinity was also found to exist in the water of the Shkotovka and Artemovka rivers, respectively.

“…Dalam A Manual on Technical Aspects of The United Nations Convention on The Law of The Sea-1982 (TALOS), mulut sungai merupakan tempat mengalirnya sungai ke laut. Menurut Mikhailov & Gorin (2012) area mulut sungai (sinonim: mulut sungai) merupakan objek geografi yang spesifik yang meliputi area aliran sungai sampai tubuh air penerimanya (samudera, laut ataupun danau). Mulut sungai sendiri dapat dibagi menjadi lima tipe berdasarkan karakter morfologinya, yaitu simple, estuarine, estuarine-deltaic, deltaicestuarine, dan deltaic.…”

“…Identifikasi tipe mulut sungai diperlukan untuk mengetahui apakah sungai mengalir langsung ke laut atau melalui estuari terlebih dahulu dan mengetahui ada tidaknya delta. Berdasarkan klasifikasi dari Mikhailov & Gorin (2012) mulut sungai dibagi menjadi lima tipe berdasarkan morfologinya, yaitu simple, estuarine, estuarine-deltaic, deltaic-estuarine, dan deltaic. Identifikasi tipe mulut sungai dilakukan dengan melihat morfologi mulut sungai (berdelta atau tidak) dan menentukan ada tidaknya estuari.…”

Indonesia sebagai negara kepulauan berhak menetapkan perairan pedalaman dengan menarik garis penutup mulut sungai, garis penutup teluk, dan garis penutup pelabuhan berdasarkan UNCLOS 1982 pasal 9, 10, dan 11. Melalui koordinasi di bawah Kementerian Koordinator Bidang Kemaritiman dan Investasi, hingga tahun 2018 Indonesia telah melakukan identifikasi penutupan teluk-teluk. Identifikasi terhadap garis penutup mulut sungai dan pelabuhan belum dilakukan karena belum memiliki standard dalam metode penarikannya. Berdasarkan pasal 9 UNCLOS 1982, jika sungai mengalir langsung ke laut, maka garis dasar ditarik lurus melewati mulut sungai di antara tepi sungai pada garis air rendah. Dalam pasal tersebut kriteria sungai yang mengalir langsung ke laut dan titik acuan penarikan garis mulut sungai masih belum dijelaskan secara terperinci, sehingga masih sulit diikuti secara teknis. Identifikasi tipe mulut sungai diperlukan untuk menentukan apakah sungai mengalir langsung ke laut ataukah melalui estuari terlebih dahulu. Jika sungai mengalir langsung ke laut, maka prinsip pasal 9 UNCLOS 1982 dapat digunakan. Jika sungai tidak mengalir langsung ke laut, namun melalui estuari, maka prinsip pasal 9 UNCLOS 1982 tidak dapat digunakan, sehingga diperlukan pendekatan metode teknis lain yang lebih relevan. Penelitian ini bertujuan untuk menentukan metode penarikan garis penutup mulut sungai untuk penetapan perairan pedalaman. Penelitian ini menggunakan metode studi literatur dari dokumen perundang-undangan, dokumen konvensi, dan dokumen teknis terkait. Hasil yang diperoleh adalah rekomendasi metode yang dapat digunakan untuk penarikan garis penutup mulut sungai. Penarikan garis penutup mulut sungai dilakukan dengan empat langkah utama, yaitu 1) identifikasi tipe mulut sungai 2) menentukan metode penarikan garis penutup mulut sungai 3) menentukan titik acuan garis penutup mulut sungai 4) menarik garis penutup mulut sungai.

“…However, estimates of nutrient loading to nearshore areas are often made in association with monitoring stations located upstream of any direct lake or ocean influence [9]. These estimates do not include the effect of low-flow, depositional areas associated with the rivermouth itself, where water residence times are longer than in streams[10], [11]. These wetlands and embayments associated with rivermouths and estuaries may significantly alter nutrient delivery to the nearshore [12], [13].…”

“…We predict that land cover indicators of depositional or low-flow habitats such as wetlands and open surface waters (i.e., lake area) will be negatively related to consumer tissue δ 15 N. Finally, we predict that the magnitude of land cover effects on consumer tissue δ 15 N will vary with ecosystem type (river and rivermouth). Aquatic processes that remove or retain N are more effective in lower-flow environments [7], and by definition rivermouths are areas where lotic waters merge and become more lentic [10], [11]. Removal of agricultural N in rivermouths would lessen the strength of relationships between watershed agriculture and the N present in consumers (as observed previously [8]).…”

Rivermouth Alteration of Agricultural Impacts on Consumer Tissue δ15N

et al. 2013

Terrestrial agricultural activities strongly influence riverine nitrogen (N) dynamics, which is reflected in the δ15N of riverine consumer tissues. However, processes within aquatic ecosystems also influence consumer tissue δ15N. As aquatic processes become more important terrestrial inputs may become a weaker predictor of consumer tissue δ15N. In a previous study, this terrestrial-consumer tissue δ15N connection was very strong at river sites, but was disrupted by processes occurring in rivermouths (the ‘rivermouth effect’). This suggested that watershed indicators of N loading might be accurate in riverine settings, but could be inaccurate when considering N loading to the nearshore of large lakes and oceans. In this study, the rivermouth effect was examined on twenty-five sites spread across the Laurentian Great Lakes. Relationships between agriculture and consumer tissue δ15N occurred in both upstream rivers and at the outlets where rivermouths connect to the nearshore zone, but agriculture explained less variation and had a weaker effect at the outlet. These results suggest that rivermouths may sometimes be significant sources or sinks of N, which would cause N loading estimates to the nearshore zone that are typically made at discharge gages further upstream to be inaccurate. Identifying definitively the controls over the rivermouth effect on N loading (and other nutrients) will require integration of biogeochemical and hydrologic models.
