Author Guidelines

Limnology and Oceanography e-Lectures  are intended as a practical resource for educators and researchers, and are provided to all ASLO members. We encourage e-Lecture authors to utilize their expertise in a given subject area to present the material in an informative and engaging style.

Following the guidelines below will ensure your lecture is consistent and compatible with different operating systems, and contains all the necessary elements for a successful presentation.

Since e-Lectures is classified as a full-fledged ASLO publication with ISSN number, vetted by experts in the field, authors can include their lectures on a CV as peer-reviewed publications.

As with any scientific publication, the peer review process gives the e-Lecture author the opportunity to improve their lecture and ensure that there are no flaws or gaps.

These guidelines cover:

Submitting your e-Lecture (lecture submission and editorial decisions)
e-Lecture Categories
e-Lecture Design and Content (templates, style, permissions)
Technical Guidelines (fonts, graphics, video)

You might want to look at our published e-Lectures to see how other lectures were created.

Editorial decisions

The Managing Editor may decline to consider a manuscript for several reasons, including inadequate evidence that the lecture is substantially new and promising, poor preparation, an unclear, non-detailed presentation, or a lack of adherence to the journal's guidelines for manuscript preparation. Once a manuscript has been accepted for consideration, it will be assigned to an Associate Editor who will ultimately recommend one of four decisions:

  • Accept
  • Accept after suitable revision
  • Reject with invitation for resubmission
  • Reject

The reviews along with the Associate Editor’s final recommendations will then be sent to the e-Lecture Editor-in-Chief for final acceptance and publication.

e-Lecture categories

Your lecture for Limnology and Oceanography e-Lectures must fall into one of these three categories:

  • Fundamentals in Limnology and Oceanography: Fundamentals in Limnology and Oceanography are a suite of lectures intended for a full semester, with each lecture designed for a 45-minute period. Instructive, conceptual slides that convey basic information and enable transition between ideas are best for this type of lecture. Lectures for this category support traditional and core classes typically offered at post-secondary institutions at the undergraduate and graduate level (e.g. Introductory Limnology or Oceanography, Physical/Geological/Chemical/Biological Limnology or Oceanography, Marine Ecology, Hydrology, Biogeochemistry, Modeling, or Paleogeology).

  • Special Topics in Limnology and Oceanography: Special topics lectures are reserved for specific ideas or events in which experts in their field can introduce the latest aquatic-related scientific topics within a 45-minute period.

  • Contemporary Issues in Limnology and Oceanography: Contemporary Issues lectures are solicited for ideas or events in Limnology and Oceanography that are topical and highly relevant to the general public. Examples of such issues would be invasive species, impacts of warming temperatures on aquatic ecosystems, contaminant loading, eutrophication, toxic algae, ocean acidification, oil spills, or fisheries crashes. Both a broad overview lecture (one 45-minute period) as well a small suite (i.e. three to five 45-minute periods) of detailed lectures will need to be offered with the Contemporary Issues lectures.

e-Lecture Design and Content

PowerPoint Lecture elements

  • Template: Please use the Limnology and Oceanography eLectures  PowerPoint Template as the master slide layout.

    The template creates a footer on each slide, with placeholders for the author name, doi number, and ASLO logo. To use the template, go to “Format>Slide Theme>From File…” and select the template (make sure you’ve downloaded the template someplace on your computer where you can easily find it).

    To edit the author name, go to “View>Master>Slide Master” and replace the text with the author’s name. Please do not change the font or size. The doi and ASLO logo should also remain untouched.

  • Lecture format and Slide design: Plan your lecture to be given within a 45-minute period. A general rule for slides of moderate complexity is 1 minute per slide. Except for rapid-fire photographs, presentations in excess of 50 slides are strongly discouraged.

    Keep the design clean and simple – try not to crowd slides with too much information. Avoid harsh color combinations, flashing graphics and other distractions.

    To facilitate effective usage of the lecture, each slide should be accompanied by bulleted descriptive information (i.e. 2-4 bullets) about that slide. This bulleted information can be incorporated into the slide layout, added in the presenter notes section of the PowerPoint slide, or included in a supplementary lecture notes document.

    Authors are also encouraged to make use of multimedia, such as video, animation, and audio clips in the creation of lectures.

  • Title slide: The title slide should include your name, professional affiliation(s), co-authors (if any), and your contact information. Incorporating a nice, attention-getting background image will add appeal.

  • Introduction: Include a few introductory slides to establish and define the lecture topic and context, and provide an outline of the presentation if necessary.

  • Summary: Provide a slide at the end of your lecture that provides a summary of the main take-home points of your e-Lecture

  • Acknowledgments: Your acknowledgments should contain brief statements about granting agencies, notable aid from individuals and institutions, and potential conflicts of interest. This is to be placed at the end of the lecture.

  • References List

e-Lecture abstract

Please provide a brief abstract of your lecture. This abstract should provide a summary to users, outlining the scope of the lecture, as well as indicating the targeted student audience. Lecture summaries and the keywords within are essential as they help generate optimal internet search results, bringing attention to your e-Lecture.

Lecture notes

You must provide a text document of lecture notes for the lecture user. These notes typically contain additional information not displayed in the presentation. You can also add the notes in the section below each slide.

Reading lists

Along with your lecture, please include 2 accompanying reading lists: one for presenters, and one for the audience. These lists don’t need to be extensive; a few key readings are preferred.

For all of the above, any text document format is acceptable, as these will be converted to PDF.

Image credits and Permissions

If your lecture contains images or graphics used from other sources, they must be properly attributed, and copyright permissions must be obtained from that publisher/source.

If you use third party images and graphics (such as from stock photography outlets), please include the licensing agreement information from those sources. In some cases, if there are usage limitations, stock images cannot be used. If you don’t have licensing agreements for any stock images used in your e-Lecture, please do not include those images.

Authors also have access to the ASLO Image Library and are encouraged to utilize this resource as these images can be used in ASLO publications without the need for copyright permissions.

Publishing agreement

Authors of accepted manuscripts must submit a publishing agreement form, assigning copyright to ASLO and agreeing to abide by the rules of use of the published article. This form can be returned to the managing editor at any time following manuscript submission (in which case it is conditional upon acceptance), and must be returned before an accepted manuscript can enter editorial review. In certain cases, copyright will be owned by the author, or the author's employer or institution, rather than by ASLO. Please contact the Editorial Office if your organization requires that it retain copyright.

Technical guidelines


Using common fonts will eliminate most formatting and compatibility problems. The following fonts are generally handled well by both PC and Mac platforms:

  • Arial
  • Tahoma
  • Times
  • Trebuchet MS
  • Verdana

Since mathematics symbols and special characters typically will not appear correctly on other user's computers, please convert those characters to GIF images and place them into your presentation. Converting characters into images can be done within PowerPoint.

Graphics and Multimedia

For best visual results, photographs should be embedded in PowerPoint as JPG files. Use the highest resolution possible when optimizing your own photos. Simple illustrations, diagrams, and formulas should be embedded as GIF files. A general rule of thumb is: jpg for photographs, gif for graphics. If you work with pict, png, bmp, pdf, eps or other image formats, please convert them to JPG or GIF for your PowerPoint file.

Video and Audio

If your lecture includes video, it must be converted to MPG-1 (.mpg) format. All other formats will cause playback errors.

If you are using audio files, MP3 and WAV are acceptable formats. MP3 files compressed at 256k will sound the best.

Slide transitions

If you are adding slide transitions, use only the simple styles, as the sophisticated transitions do not work well amongst various versions of PowerPoint.
