이민지,김동선,김영옥,손문호,문창호,백승호,LEE, MIN-JI,KIM, DONGSEON,KIM, YOUNG OK,SOHN, MOONHO,MOON, CHANG-HO,BAEK, SEUNG HO 한국해양학회 2016 바다 Vol.21 No.1

2014년 울산만 내, 외측 해역에서 해양환경의 계절 변화가 식물플랑크톤 군집의 공간 분포에 미치는 영향을 파악하였다. 울산만을 태화강 하구에 위치한 내측과 외양 영향을 강하게 받는 외측으로 나누어, 내측과 외측의 환경 차이를 t-test로 검증하였다. 수온은 동계(t = -5.833, p < 0.01)와 추계(p > 0.05)에는 외측이 높았고, 춘계(t = 4.247, p < 0.01)와 하계(t = 2.876, p < 0.05)에는 내측이 높았다. 염분은 추계를 제외한 모든 계절에 내측에서 외측보다 유의하게 낮았다(p < 0.01). 동계에는 수층 혼합에 의해 전 수층에서 영양염 농도가 높았고, 하계에는 담수 유입으로 내측 표층에서 현저하게 높았다. 크기 분획된 Chl. a 양은 $20{\mu}m$보다 작은 크기의 nano, pico식물플랑크톤의 양이 많았다. 극미소 식물플랑크톤은 영양염 농도가 낮은 외양 환경에서 적응력이 높은데 이러한 결과는 조사해역이 외양의 영향을 강하게 받고 있음을 시사한다. 춘계와 하계에는 내측 정점을 중심으로 유글레나류 Eutreptiella gymnastica의 밀도가 특이적으로 높았다. 이는 강우 후 많은 담수가 유입되어 저염분 환경이 조성되고 DIN (nitrate+nitrite, ammonium)이 대량 공급되었기 때문이다. 하계에는 태화강으로부터 다량의 담수가 공급되어 담수미세 남조류 Oscillatoria sp., Microcystis sp.가 내측 정점(1-5)을 중심으로 높은 밀도로 출현하였다. 추계와 동계에는 규조류와 은편모류가 우점하였다. 높은 현존량을 보인 중심 규조류Chaetoceros 속은 성층 약화로 저층에서 공급되는 영양염류의 영향을 받아 빠르게 성장하였고, 은편모조류는 다른 식물플랑크톤의 상대적인 성장 둔화로 기회적으로 우점하였다. 결과적으로 울산만은 강우기인 춘계와 하계에 태화강의 영향을 강하게 받아 내측 정점을 중심으로 저염분, 고영양염 환경이 유지되었고, 추계와 동계에는 만 외측 외양수의 영향을 크게 받았으며, 식물플랑크톤 군집은 크게 이 두가지 환경요인에 의해 계절적으로 제어되는 것으로 판단되었다. To assess the relationship between environmental factors and seasonal phytoplankton community structure, we investigated abiotic and biotic factors in Ulsan Bay, Korea. We divided the bay into two areas based on geographical characteristics and compared the difference in each factor between inner and outer bay with t-test statistics. As a result, temperature in the outer bay was higher than that of the inner bay during winter (t = -5.833, p < 0.01) and autumn (p > 0.05). However, opposite trend was observed during spring (t = 4.247, p < 0.01) and summer (t = 2.876, p < 0.05). Salinity was significantly lower in the inner bay than in the outer bay in winter, spring, and summer (p < 0.01). However, the salinity was not significantly different between the inner and the outer bay in the autumn (p > 0.05). In particular, high nutrient concentration was observed in most stations during winter season due to vertical well mixing. The nutrient concentration was significantly higher in surface layers of inner bay after rainfall, particularly in the summer. The relative contribution (approximately 70%) of < $20{\mu}m$ (nano and pico) size phytoplankton was increased in all seasons with continuously low nutrients from the offshore water due to their adaption to low nutrient without other large competitors. Interestingly, high population of Eutreptiella gymnastica was kept in the inner bay during the spring and summer associated with high DIN (nitrate+nitrite, ammonium) after river discharge following rainfall, suggesting that DIN supply might have triggered the increase of Eutreptiella gymnastica population. In addition, high density of freshwater species Oscillatoria sp. and Microcystis sp. were found in several stations of the inner bay that were provided with large amounts of freshwater from the Tae-wha River. Diatom and cryptophyta species were found to be dominant species in the autumn and winter. Of these, centric diatom Chaetoceros genus was occupied in the outer bay in the autumn. Cryptophyta species known as opportunistic micro-algae were found to have high biomass without competitors in the inner bay. Our results demonstrated that Ulsan Bay was strongly affected by freshwater from Tae-wha River during the rainy season and by the surface warm water current from the offshore of the bay during dry season. These two external factors might play important roles in regulating the seasonal phytoplankton community structures.

이민지,한경수,Lee, Min-Ji,Han, Kyung-Soo 한국공간정보학회 2010 한국공간정보학회지 Vol.18 No.5

본 연구에서는 툰드라-타이가 경계영역의 변화를 확인하기 위해 식생의 분포 변화를 관측하였다. 툰드라-타이가 경계영역은 인간 활동 혹은 기후 변화에 따른 신호로 나타나는 식생패턴의 이동을 관측하기 위해 사용된다. 극지의 툰드라-타이가 경계영역은 조금의 변화에 대해서도 두드러진 반응을 관찰 할 수 있으므로 다른 곳에 비해 기후변화에 대한 반응과 확인이 명확하다. 연구 자료로서 2000년에서 2009년까지 총 10년간 매년 8월을 Terra위성 MODIS(MODerate resolution Imaging Spectroradiometer) 센서로부터 취득한 LAI(Leaf Area Index) 8-Day 자료를 사용하였고, 보조 자료로서 기후지도와 GLC 2000(Global Land Cover 2000)토지피복 지도를 사용하였다. 본 연구에서는 엽면적 지수의 10년치 장기간 자료를 이용하여 시 공간 분석과 식생의 밀도가 저조한 지역을 중심으로 위도대 별, 토지피복 별분석을 시행하였다. 연구대상 지역에 대하여 엽면적 지수의 기준값을 바탕으로 한 분석에서 2000년에서 2009년까지 LAI의 변화를 확인하였다. 툰드라 기후에서 식생의 감소가 일어난 면적($22,372km^2$) 보다 식생의 성장을 보인 면적은 $730,325km^2$ 로서 식생의 발달을 확인할 수 있었다. 또한 위도대 별 면적 분석을 통해 위도 $62^{\circ}$ N의 주위와 위도 $64^{\circ}$ N~$66^{\circ}$ N을 중심으로 면적 증가가 나타났으며, 툰드라-타이가 경계영역의 식생은 2000년부터 2009년까지 전반적인 증가 추세가 나타났다. 전체적으로 식생 감소가 일어나는 면적 변화는 다소 적은 것에 비해 식생의 성장과 발달이 일어나는 곳의 면적은 크게 증가하는 것을 확인하였다. This study observed distribution of vegetation to confirm change of tundra-taiga boundary. Tundra-taiga boundary is used to observe the transfer of vegetation pattern because it is very sensitive to human activity, natural disturbances and climate change. The circumpolar tundra-taiga boundary could observe reaction about some change. Reaction and confirmation about climate change were definite than other place. This study used Leaf Area Index(LAI) 8-Day data in August from 2000 to 2009 that acquire from Terra satellite MODerate resolution Imaging Spectroradiometer(MODIS) sensor and used K$\"{o}$ppen Climate Map, Global Land Cover 2000 for reference data. This study conducted analysis of spatial distribution in low density vegetated areas and inter-annual / zonal analysis for using the long period data of LAI. Change of LAI was confirmed by analysis based on boundary value of LAI in study area. Development of vegetation could be confirmed by area of grown vegetation($730,325km^2$) than area of reduced vegetation ($22,372km^2$) in tundra climate. Also, area was increased with the latitude $64^{\circ}$ N~$66^{\circ}$ N as the center and around the latitude $62^{\circ}$ N through area analysis by latitude. Vegetation of tundra-taiga boundary was general increase from 2000 to 2009. While area of reduced vegetation was a little, area of vegetation growth and development was increased significantly.
