Connect with other aquatic scientists from around the world at the ASLO 2019 Aquatic Sciences Meeting!

In 2019, ASLO will meet in San Juan, Puerto Rico. The theme of this meeting will be Planet Water: Challenges and Successes/Planeta Agua: Retos y exitos. The dates of the meeting run from Saturday to Saturday, with the scientific portion taking place Sunday to Friday (24 February to 1 March). We are encouraging sign-up for a variety of community service projects that will be organized to help those in Puerto Rico as they continue to recover from the devastating hurricanes. We invite you to participate in this dialogue among limnologists and oceanographers from around the world. Our conference theme is particularly fitting as we face challenges with water on a global scale as well as on the island of Puerto Rico.

Special Sessions

We welcome proposals for special sessions on topics relevant to all aquatic systems. We hope that you will consider developing an idea for a special session that will contribute to a lively conference. In addition to special sessions, the program committee has provided an updated, modernized list of contributed sessions. Before submitting a special session proposal, please review the list of contributed sessions (see below).

Special session proposals should identify at least two, but no more than six, co-organizers and should include an informative session title and a short description of the session. One of the session co-chairs must be identified as the session’s lead contact for the meeting committee.

Before You Start - Do you have a login?

This year we are requiring that you have a login to our new website to submit. If you are a member you already have a login. If you are not an ASLO member, you may set up a guest account. This will make it easier for you to review and edit your submission, and make it easier to register for our event later.

Guidelines for Session Nominations

Session nominations must be submitted using the online form (see submission link at right). At least two co-chairs who plan to attend are required. Session chairs who attend must register for the meeting. Session titles should be 255 characters or less. Session descriptions should be limited to 200 words and should be broad enough to include all interested researchers, regardless of affiliation or funding sources.

Session Organization

Once a session is accepted, session organizers should solicit abstract submissions to their session. Sessions will be scheduled by the planning committee. Once a session is set with a specific list of presentations, those designated for poster and oral presentation will be determined by the organizers.

Contributed Sessions

To reflect current science trends, the program committee has modernized the topics covered in the contributed sessions.  In doing so, we strive to revitalize participation in contributed sessions, increase cross fertilization of ideas between limnologists and oceanographers and adjacent fields, and reduce overlap among concurrent sessions.  The scientific committee for the meeting strongly encourages sessions that will not overlap with the topics of contributed sessions. Contributed session topics cover those most frequently presented at ASLO Aquatic Science Meetings – so please read the new list.

Authors who submit a paper to a contributed session will be asked to indicate if they will be willing to chair the session. The planning committee will select two or three speakers to be invited session chairs. These invited chairs will be given the option of naming one of the speakers in their session to be a featured presenter.

Thank You!

Thank you very much for your interest in participating in the 2019 Aquatic Sciences Meeting by suggesting a session. As you probably know, sessions form a large part of the structure of our meetings, and the Organizing Committee relies upon individuals to come forward with ideas for the best and most exciting topics. The Committee will review the submitted suggestions and develop a meeting plan that incorporates these ideas. Your contribution is greatly appreciated!
