 September 2 – Welcome to Limnology Laboratory!

September 4 – Bring raingear to lab today. We will go out on the lake in the rain, unless there are thunderstorms.

The Web of Science database can be found at the link below. This database should be used to find articles for assignment #1. http://apps.isiknowledge.com.ezproxy.library.wisc.edu/WOS_GeneralSearch_input.do?product=WOS&search_mode=GeneralSearch&SID=3CgeNAE39ABa4GA6o5O&preferencesSaved=

September 8 – Prepare for Lab 3 in your lab manual, pH, acid neutralizing capacity and conductivity, this week. We will do the dissolved oxygen lab, Lab 2 in your manual, next week.

October 6 – This week in lab you will be performing some statistical analyses using the 2007 Multi Lake dataset using the statistics program R. Here are the needed files:

StatsHandout-08

Week6_Data

Annova Script

Regression Script

Tukeys Test Script

T test Script

October 17 – For the lab this week only Lab Questions 1 and 3 are due. The rest will be due with the lab questions next week.

                        For those of you doing projects on streams here is list of Wisconsin streams and a map with general locations from the USGS. It includes data that may help you in choosing which              stream to work on for your project such as watershed size, flow rate, substrate types, etc.

October 24 – This week your take home quizzes are due on the same day your lab questions are usually due and Lab Questions 7 and Lab Questions 6 (#2 and 4) are due on Monday.

                         Here is summary data for silica, phosphorus and chlorophyll-a from Lake Mendota to use in answering your questions. You may also need the Trout Lake trip data which can be found on the assignments webpage above.

October 29 – Here are the chlorophyll-a and zooplankton data from the Trout Lake trips. Use the Chl-a (ug/L) and Pheophyton (ug/L) columns for your chlorophyll analyses and the zooplankton concentration values for your zooplankton analyses. Feel free to summarize or combine data as you see fit for your hypotheses, just make sure to explain any data manipulation in your papers.

 Two students will be sending missing chlorophyll-a data to the whole classlist soon. If you have any of the missing data we will leave it up to you to get it to the rest of your fieldwork team (the rest of the lab) at this point. 

November 3 – You will be turning in a first draft of your multi-lakes paper (introduction, methods and results) and  peer reviewing each others drafts during lab this week. Please bring four copies of your multi-lake paper draft to class. Three of the copies (for peer review) should not have your name on them and one copy should include your name (for the TAs to grade).

November 6 – Good luck in writing the first draft of your Multi-lake paper. Here are the writing presentation and peer review rubric from lab this week to help you in know what we are looking for in your first draft. Appendix B of your lab manual also offers good advice for writing a scientific paper. 

December 1 – This week in lab you will use LTER data from Lake Mendota and work in small groups to create graphs and present seasonal trends in eight different lake variables that we have studied over the course of the semester. Data for this is below:

Temperature

Dissolved Oxygen

Secchi Depth_Chlorophyll

Dissolved Inorganic Carbon

pH

Dissolved Reactive Silica

Total Phosphorus

Soluble Reactive Phosphorus
