The 4th day at QUBS – geocaching extravaganza. August 18th

Post by Team Eel.

Lost in the woods?

Today we started off the day with a GPS scavenger hunt, otherwise known as “geocaching”. We were given the UTM coordinates for 6 locations on Queen’s University Biological Station property that contained fluorescent pink flagging tape and biological questions that our groups had to answer. We were also given a GPS in order to help us find these locations – our group plugged in each location as a “waypoint” and traveled along the most efficient route in order to retrieve all 6 questions. Unfortunately there was a typo in one of the location’s coordinates, resulting in some interesting escapades in an attempt to find said location. Our group personally tried climbing over fences, hills and navigating through wetlands to try and find the location, all to no avail of course. Our GPS also died halfway through the hunt, so we partnered up with two other teams. It was really fun using the GPS and watching the arrow representing our current position slowly move towards each respective location. It was also rather amusing (though not at the time!) to see a trail of our attempts to locate the missing location with the typo in its coordinates.

After the geocaching exercise we retrieved a NAME net with two canoes that we had set up along

Geocaching - answering THE QUESTION!

the shoreline the previous day. We caught a variety of small fish such as bluegill, pumpkinseed, rockbass and yellow perch. Unfortunately one of the captured fish jumped out of the bucket and landed underneath a section of the dock that we could also reach through a small crack. Several of the students tried in vain to rescue the small bluegill by flushing it with water and attempting to use newly-found chopstick skills to fish it out of the crack. After about 20 minutes they were successful in removing it, but even after some mouth-to-mouth the fish slowly passed away. However, the fish did not go to waste as it was tossed back in the water where some larger bluegills happily consumed it.

Following the retrieval of the NAME net, students were assigned to one of two wetlands in order to complete a wetland analysis for use in a future assignment. Students collected data on the dominant plant and animal species present, the percentage and fractional area of vegetative forms, the water quality and chemistry, soil types, water sources and much more information that will be compiled and compared at the end of the course. Our wetland, called Beaver Marsh, was covered in a variety of tall shrubs and emergents, with very little open water. It was interesting to perform the analysis ourselves as it gave us a better appreciation of the work that goes into the assessment of wetlands and other habitats.

After we compiled data from the two wetlands we had dinner and then attended a guest lecture by Dr. Emily Gonzales. She is working at St Lawrence Island National Park. She introduced about developing of National Park in Canada. Following the guest speaker, we had two students presentation. The ebullient Edwina Dai talked about Farm Fishing in Canada. The incomparable David Chang presented the relationship between agricultural and freshwater ecosystems.

崭新的一天从GPS定向(或者寻宝)开始了!我们每个小组都拿到了6个在QUBS的UTM坐标。在每个地点都能找到用粉红色丝带系的一个生物学问题,我们必须找到这些地点,然后回答出这些生物学问题。当然,GPS是必不可少的。我们小组“创造性地”把这6个地点的坐标输入到了GPS中,这样我们就能在GPS中的位点的指引下找到最优路线。但是其中一个位点的坐标信息有误,这让我们在寻找它的途中绕了大圈子,犯了一些有趣的小错误。比如翻越栅栏,爬上小山,横越湿地,结果都一无所获。我们GPS的电池也在半路上没电了,因此我们不得不和其他的小组合作。利用GPS最有趣的地方之一就是看随着我们的前进方向和所在位置的改变,箭头方向和在地图上的位置也跟着改变。看着我们的位置在那个错误坐标附近徘徊也非常有趣!

有趣的寻宝活动之后,我们用两艘独木舟回收了设在船坞附近岸边的NAME鱼网。网中我们发现了一些bluegill,pumpkinseed,rock bass和yellow perch之类的小鱼。不幸的是,一条小bluegill跳出了水桶还陷在了船坞的木板里。几个学生试图用细树枝把它夹出来,同时不断给它浇湖水。经过了大约20分钟的努力,小鱼终于被救了出来。但就算给它做人工呼吸,小鱼还是渐渐死去了。我们没有办法,只能将其放回湖中,至少它还能被其他大太阳鱼吃了当午餐。

下午我们所有人被分成两组,前往两个不同的湿地进行湿地评估。一些学生要收集优势植物和动物的信息,植被种类的覆盖比例,一些学生要收集水化学的信息,土壤种类,水源,以及其他很多信息,这些数据最后要汇总,以供大家完成最后的评估报告。我们调查的湿地是河狸湿地,那里被很多高大灌木和水生植物覆盖,但只有很少的开放水面。我们独立完成这一评估对我们理解整个科学评估和了解湿地和其他生境很有意义。

之后我们汇总了两个湿地的信息。晚饭后我们听了Emly Gonzaks关于圣罗伦斯岛国家公园的报告。她介绍了很多加拿大的国家公园。之后我们的两个学生分别作了报告。Edwina Dai介绍了加拿大的养鱼业,而David Chang则介绍了农业和淡水生态系统的关系。

好了,今天就是这样了!
